Improves the derive macro for `SettingsUi` so that titles generated from
struct and field names are shown in title case, and toggle button groups
use title case for rendering, while using lower case/snake case in JSON

Closes #ISSUE

This PR includes the necessary work to get `EditorSettings` showing up
in the settings UI. Including making the `path` field on
`SettingsUiItem`'s optional so that top level items such as
`EditorSettings` which have `Settings::KEY = None` (i.e. are treated
like `serde(flatten)`) have their paths computed correctly for JSON
reading/updating.

It includes the first examples of a pattern I expect to continue with
the `SettingsUi` work with respect to settings reorganization, that
being adding missing defaults, and adding explicit values (or aliases)
to settings which previously relied on `null` being a value for optional
fields.

Release Notes:

- N/A *or* Added/Fixed/Improved ...

Closes #ISSUE

Initially, the `SettingsUi` trait was tied to `Settings`, however, given
that the `Settings::FileContent` type (which may be the same as the type
that implements `Settings`) will be the type that more directly maps to
the JSON structure (and therefore have the documentation, correct field
names (or `serde` rename attributes), etc) it makes more sense to have
the deriving of `SettingsUi` occur on the `FileContent` type rather than
the `Settings` type.

In order for this to work a relatively important change had to be made
to the derive macro, that being that it now "unwraps" options into their
inner type, so a field with type `Option<Foo>` where `Foo: SettingsUi`
will treat the field as if it were just `Foo`, expecting there to be a
default set in `default.json`. This imposes some restrictions on what
`Settings::FileContent` can be as seen in 1e19398 where `FileContent`
itself can't be optional without manually implementing `SettingsUi`, as
well as introducing some risk that if the `FileContent` type has
`serde(default)`, the default value will override the default value from
`default.json` in the UI even though it may differ (but it should!).

A future PR should probably replace the other settings with `FileContent
= Option<T>` (all of which currently have `T == bool`) with wrapper
structs and have `KEY = None` so the further niceties
`derive(SettingsUi)` will provide such as path renaming, custom UI, auto
naming and doc comment extraction can be used.

Closes #ISSUE

Adds a first draft of a way for "Dynamic" settings items to be added,
where Dynamic means settings where multiple sets of options are possible
(i.e. discriminated union, rust enum, etc). The implementation is very
similar to that of `Group`, except that instead of rendering all of it's
descendants, it contains a function to determine _which_ descendant to
render, whether that be a single item or a nested group of items.
Currently this is done in a type-unsafe way with indices, a future
improvement could be to make the API more type safe, and easier to
manually implement correctly.

An example of a "Dynamic" setting is `theme`, where it can either be a
string of the desired theme name, or an object with `mode: "light" |
"dark" | "system"` as well as theme names for `light` and `dark`. In the
system implemented by this PR, this would become a dynamic settings UI
item, where option `0` is a single item, the theme name selector, and
option `1` is a group, containing items for the `mode`, and
`light`/`dark` options.

This updates `editor: rewrap` to work within doc comments, based on the
code that extends such comments on newline. I added some tests, and I've
tested it out in JS, C and PHP. (Though PHP depends on
https://github.com/zed-extensions/php/pull/40)

Closes #19794
Closes #18221

**Caveat:**
~~This will not rewrap an existing single-line block comment, such as
the one provided in #18221:~~ this will now rewrap as expected
```c
/* we can triangulate any convex polygon by picking a vertex and connecting it to the next two vertices; we first read two vertices, and then, for every subsequent vertex, we can form a triangle by connecting it to the first and previous vertex */
```
However, it will rewrap a similar comment if it is shaped like a doc
comment. In other words, this will rewrap as expected:
```c
/* 
 * we can triangulate any convex polygon by picking a vertex and connecting it to the next two vertices; we first read two vertices, and then, for every subsequent vertex, we can form a triangle by connecting it to the first and previous vertex 
 */
```

This seems like a reasonable improvement and limitation to me,
especially as a first step.

cc @smitbarmase because I think that you've been making a lot of the
`newline` and `rewrap` changes recently. (Thank you for those, by the
way!)

Release Notes:

- Added support for rewrap in block comments.

Release Notes:

- Added setting `rounded_selection` to disable rounded corners for text
selection.

Currently when we render text with differing styles adjacently we might
form a ligature between the text, causing the ligature forming
characters to take on one of the two styles. This can especially become
confusing when a ligature is formed between actual text and inlay hints.

Annoyingly, the only ways to prevent this with core text is to either
render each run separately, or to insert a zero-width non-joiner to
force core text to break the ligatures apart, as it otherwise will merge
subsequent font runs of the same fonts.

We currently do layouting on a per line basis and it is unlikely we want
to change that as it would incur a lot of complexity and annoyances to
merge things back into a line, so this goes with the other approach of
inserting ZWNJ characters instead.

Note that neither linux nor windows seem to currently render ligatures,
so this only concerns macOS rendering at the moment.

Release Notes:

- Fixed ligatures forming between real text and inlay hints on macOS

Follow up of https://github.com/zed-industries/zed/pull/33334

After chatting with @MrSubidubi we found out that he had an old defaults
setting (most likely from when he encountered a previous window tabbing
bug):
```
❯ defaults read dev.zed.Zed-Nightly
{
    NSNavPanelExpandedSizeForOpenMode = "{800, 448}";
    NSNavPanelExpandedSizeForSaveMode = "{800, 448}";
    NSNavPanelExpandedStateForSaveMode = 1;
    NSOSPLastRootDirectory = {length = 828, bytes = 0x626f6f6b 3c030000 00000410 30000000 ... dc010000 00000000 };
    "NSWindow Frame NSNavPanelAutosaveName" = "557 1726 800 448 -323 982 2560 1440 ";
    "NSWindowTabbingShoudShowTabBarKey-GPUIWindow-GPUIWindow-(null)-HT-FS" = 1;
}
```

> That suffix is AppKit’s fallback autosave name when no tabbing
identifier is set. It encodes the NSWindow subclass (GPUIWindow), plus
traits like HT (hidden titlebar) and FS (fullscreen).

Which explains why it only happened on the Nightly build, since each
bundle has it's own defaults. It also explains why the tabbar would
disappear when he activated the `use_system_window_tabs` setting,
because with that setting activated, the tabbing identifier becomes
"zed" (instead of the default one when omitted) for which he didn't have
the `NSWindowTabbingShoudShowTabBarKey` default.

The original implementation was perhaps a bit naive and relied fully on
macOS to determine if the tabbar should be shown. I've updated the code
to always hide the tabbar, if the setting is turned off and there is
only 1 tab entry.

While testing, I also noticed that the menu's like 'merge all windows'
wouldn't become active when the setting was turned on, only after a full
workspace reload. So I added a setting observer as well, to immediately
set the correct window properties to enable all the features without a
reload.

converted into a `AuthenticateError::Other` later.

### GitHub Vulnerability Alerts

####
[CVE-2025-58160](https://redirect.github.com/tokio-rs/tracing/security/advisories/GHSA-xwfj-jgwm-7wp5)

### Impact

Previous versions of tracing-subscriber were vulnerable to ANSI escape
sequence injection attacks. Untrusted user input containing ANSI escape
sequences could be injected into terminal output when logged,
potentially allowing attackers to:

- Manipulate terminal title bars
- Clear screens or modify terminal display
- Potentially mislead users through terminal manipulation

In isolation, impact is minimal, however security issues have been found
in terminal emulators that enabled an attacker to use ANSI escape
sequences via logs to exploit vulnerabilities in the terminal emulator.

### Patches

`tracing-subscriber` version 0.3.20 fixes this vulnerability by escaping
ANSI control characters in when writing events to destinations that may
be printed to the terminal.

### Workarounds

Avoid printing logs to terminal emulators without escaping ANSI control
sequences.

**Security Fix**: ANSI Escape Sequence Injection (CVE-TBD)

#### Impact

Previous versions of tracing-subscriber were vulnerable to ANSI escape
sequence injection attacks. Untrusted user input containing ANSI escape
sequences could be injected into terminal output when logged,
potentially allowing attackers to:

- Manipulate terminal title bars
- Clear screens or modify terminal display
- Potentially mislead users through terminal manipulation

In isolation, impact is minimal, however security issues have been found
in terminal emulators that enabled an attacker to use ANSI escape
sequences via logs to exploit vulnerabilities in the terminal emulator.

#### Solution

Version 0.3.20 fixes this vulnerability by escaping ANSI control
characters in when writing events to destinations that may be printed to
the terminal.

#### Affected Versions

All versions of tracing-subscriber prior to 0.3.20 are affected by this
vulnerability.

#### Recommendations

Immediate Action Required: We recommend upgrading to tracing-subscriber
0.3.20 immediately, especially if your application:

- Logs user-provided input (form data, HTTP headers, query parameters,
etc.)
- Runs in environments where terminal output is displayed to users

#### Migration

This is a patch release with no breaking API changes. Simply update your
Cargo.toml:

```toml
[dependencies]
tracing-subscriber = "0.3.20"
```

See discussion on #36564

Adds a simple ad-hoc substring matching pattern language which allows
skipping a bounded number of chars between matched substrings. Before
this change compiling the regex was taking ~120ms on a fast machine and
~8mb of memory. This new version is way faster and uses minimal memory.

Checked the behavior of this vs by running it against 10k licenses that
happened to be in my home dir. There were only 4 differences of behavior
with the regex implementation, and these were false negatives for the
regex implementation that are true positives with the new one.

Of the ~10k licenses in my home dir, ~1k do not match one of these
licenses, usually because it's GPL/MPL/etc.

Release Notes:

- N/A

See discussion on #36564. Makes the license regexes a less fragile by
not matching on symbols, while also excluding cases where a long file
ends with a valid license. Also adds Zlib license, a commented out test
to check all license-like files discovered in the homedir, and more
testcases.

Not too happy with the efficiency here, on my quite good computer it
takes ~120ms to compile the regex and allocates ~8mb for it. This is
just not a great use of regexes, I think something using eager substring
matching would be much more efficient - hoping to followup with that.

Release Notes:

- Edit Prediction: Added Zlib license to open-source licenses eligible
for data collection.

Closes #37025 

This PR fixes GitHub Copilot thread summary failures by removing the
unnecessary `noop` tool insertion logic. The code was originally added
as a workaround in https://github.com/zed-industries/zed/pull/30007 for
supposed GitHub Copilot API issues when tools were used previously in a
conversation but no tools are provided in the current request. However,
testing revealed that this scenario works fine without the workaround,
and the `noop` tool insertion was actually causing "Invalid schema for
function 'noop'" errors that prevented thread summarization from
working. Removing this logic eliminates the errors and allows thread
summarization to function correctly with GitHub Copilot models.

The best way to see if removing that part of code works is just
triggering thread summarisation.

Error Log:
```
2025-08-27T13:47:50-04:00 ERROR [workspace::notifications] "Failed to connect to API: 400 Bad Request {"error":{"message":"Invalid schema for function 'noop': In context=(), object schema missing properties.","code":"invalid_function_parameters"}}\n"

Closes #36564

Release Notes:

- Edit Prediction: Added various BSD licenses to open-source licenses
eligible for data collection.

## Goal 

This PR creates the initial settings ui structure with the primary goal
of making a settings UI that is
- Comprehensive: All settings are available through the UI
- Correct: Easy to understand the underlying JSON file from the UI
- Intuitive
- Easy to implement per setting so that UI is not a hindrance to future
settings changes

### Structure

The overall structure is settings layer -> data layer -> ui layer.

The settings layer is the pre-existing settings definitions, that
implement the `Settings` trait. The data layer is constructed from
settings primarily through the `SettingsUi` trait, and it's associated
derive macro. The data layer tracks the grouping of the settings, the
json path of the settings, and a data representation of how to render
the controls for the setting in the UI, that is either a marker value
for the component to use (avoiding a dependency on the `ui` crate) or a
custom render function.

Abstracting the data layer from the ui layer allows crates depending on
`settings` to implement their own UI without having to add additional UI
dependencies, thus avoiding circular dependencies. In cases where custom
UI is desired, and a creating a custom render function in the same crate
is infeasible due to circular dependencies, the current solution is to
implement a marker for the component in the `settings` crate, and then
handle the rendering of that component in `settings_ui`.

### Foundation 

This PR creates a macro and a trait both called `SettingsUi`. The
`SettingsUi` trait is added as a new trait bound on the `Settings`
trait, this allows the type system to guarantee that all settings
implement UI functionality. The macro is used to derived the trait for
most types, and can be modified through attributes for unique cases as
well.

A derive-macro is used to generate the settings UI trait impl, allowing
it the UI generation to be generated from the static information in our
code base (`default.json`, Struct/Enum names, field names, `serde`
attributes, etc). This allows the UI to be auto-generated for the most
part, and ensures consistency across the UI.


#### Immediate Follow ups

- Add a new `SettingsPath` trait that will be a trait bound on
`SettingsUi` and `Settings`
- This trait will replace the `Settings::key` value to enable
`SettingsUi` to infer the json path of it's derived type
- Figure out how to render `Option<T> where T: SettingsUi` correctly
- Handle `serde` attributes in the `SettingsUi` proc macro to correctly
get json path from a type's field and identity

For now this method is only implemented for the
`CodeContextMenu::Completions` variant, which will scroll the aside
contents for an `editor::code_context_menus::CompletionsMenu` element,
as a `ScrollHandle` is added to the aside content that is rendered.

In order to be possible to trigger this via keybindings, a new editor
action is introduced, `ContextMenuScrollAside`, which accepts a number
of lines or pages to scroll the content by.

Lastly, the default keymaps for both MacOS and Linux, as well as for
Zed's vim mode, are updated to ensure that the following keybindings are
supported when a completion menu is open and the completion item's
documentation is rendered aside:

- `ctrl-e`
- `ctrl-y`
- `ctrl-d`
- `ctrl-u`

Closes #36981 

- Add completion text and position caching to reduce redundant API calls
- Only trigger new completion requests on text changes, not cursor
movement
- Validate cursor position to ensure completions show at correct
location
- Improve end-of-line range calculation for more accurate deletions
- Extract reset_completion_cache helper for cleaner code organization
- Update completion diff algorithm documentation for clarity

Edit: Sorry this is the 2nd PR, I forgot that the forks history was
messy; I cherrypicked and cleaned it properly with this PR

Release Notes:

- supermaven: Improved caching of predictions
- supermaven: Fixed an issue where changing cursor position would
incorrectly trigger new completions

Release Notes:

- Gemini integration: Fixed a bug with permission requests when
`always_allow_tool_calls` is enabled

In the case where we fail to create an ACP connection to Gemini, only
report the "unsupported version" error if the version for the found
binary is at least our minimum version. That means we'll surface the
real error in this situation.

This also fixes incorrect sorting of downloaded Gemini versions--as @kpe
pointed out we were effectively using the version string as a key. Now
we'll correctly use the parsed semver::Version instead.

Release Notes:

Closes https://github.com/zed-industries/zed/issues/36383

The project symbols modal didn't use the buffer font and highlighted
matches through modifying the font weight, which is inconsistent with
the outline picker, which presents code in list items in a similar way,
as well as project _and_ buffer search highlighting design.

Release Notes:

Closes #36495

How it works:

For highlights (and selections) within the visible rows of the editor,
we split them row by row. This is efficient since the number of visible
rows is constant. For each row, all highlights and selections, which may
overlap, are flattened using a line sweep. This produces non-overlapping
consecutive segments for each row, each with a blended background color.

Next, for each row, we split text runs into smaller runs to adjust its
color using APCA contrast. Since both text runs and segment are
non-overlapping and consecutive, we can use two-pointer on them to do
this.

For example, a text run for the variable red might be split into two
runs if a highlight partially covers it. As a result, one part may
appear as red, while the other appears as a lighter red, depending on
the background behind it.
