Closes https://github.com/zed-industries/zed/issues/38690
Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

Updates the settings editor to collect all known settings files from the
settings store, in order to show them in the UI. Additionally adds a
fake worktree instantiation in the settings UI example binary in order
to have more than one file available when testing.

On macOS, traditionally when a keyboard shortcut is activated, the menu
in the menu bar flashes to indicate that the action was recognised.

This PR adds this functionality to GPUI, where when a keybind is pressed
that triggers an action in the menu, the menu flashes.

This reverts commit 9e7302520ec93a96a9b275a817f083b96620148e.

I run into an infinite hang in Zed nightly and used instruments and
activity monitor to sample what was going on. The root cause seemed to
be the unwrap_unchecked introduced in reverted PR.

Just making it more consistent with other pickers—button actions
justified to the right and timestamp directly in the list item to avoid
as much as possible relevant information tucked away in a tooltip where
using the keyboard will mostly be the main mean of interaction.

This reduces the size of cursor by a usize when the summary does not
require a context making Cursor usages and constructions slightly more
efficient.

This change is a bit annoying though, as Rust has no means of
specializing, so this uses a `ContextlessSummary` trait with a blanket
impl while turning the `Context` into a GAT `Context<'a>`. This means
`Summary` implies are a bit more verbose now while contextless ones are
slimmer. It does come with the downside that the lifetime in the GAT is
always considered invariant, so some lifetime splitting occurred due to
that.

The `Duration` argument in `get_models` has been unused for over a year.

The `complete` function is also unused and it has fallen behind in new
feature additions such as Authorization support. This used to exist
because ollama didn't support tools in streaming mode, `with_tools` also
existed because of that. Now however there is no reason to keep this
around.

`ChatResponseDelta ` had unnecessary `#[allow(unused)]` macros since the
fields are marked `pub`. Using `#[expect(unused)]` would've caught this.

Closes #38576

In case of inline element rendering, we can have multiple text runs on
the same display row. There was a bug in
https://github.com/zed-industries/zed/pull/37165 which doesn't consider
this multiple text runs case. This PR fixes that and adds a test for it.

Before:

src="https://github.com/user-attachments/assets/0e1a45ff-c521-4994-b259-3a054d89c4df"
/>

Release Notes:

- Fixed an issue where text could be incorrectly highlighted during
search when a line contained an inline color preview.

Closes https://github.com/zed-industries/zed/issues/38528

In the agent panel's `thread_view.rs` file, we have a `render_tool_call`
function that controls what we show in the UI for most types of tools.
However, for some of them—for example, terminal/execute and edit
tools—we have a special rendering so we can tailor the UI for their
specific needs. But... before the specific rendering function is called,
all tools still go through the `render_tool_call`.

Problem is that, in the case of the terminal tool, you couldn't see the
full command the agent wants to run when the tool is still in its
`render_tool_call` state. That's mostly because of the treatment we give
to labels while in that state. A particularly bad scenario because
well... seeing the _full_ command _before_ you choose to accept or
reject is rather important.

This PR fixes that by essentially special-casing the terminal tool
display when in the `render_tool_call` rendering state, so to speak.
There's still a slight UI misalignment I want to fix but it shouldn't
block this fix to go out.

Here's our final result:

/>

Release Notes:

- agent: Fixed terminal command not being fully displayed while in the
"waiting for confirmation" state.

Closes #31561

Release Notes:

- Implemented the select_regex Helix keymap

Prior: The keymap `s` defaulted to `vim::Substitute`

This PR removes the experimental jj bookmark picker that was added in

The current problem is that if I specify model parameters, like
`max_tokens`, in `settings.json` for an Ollama model, they do not
override the values coming from the Ollama API. Instead, the parameters
from the API are used. For example, in the settings below, even though I
have overridden `max_tokens`, Zed will still use the API's default
`context_length` of 4k.

```
  "language_models": {
    "ollama": {
      "available_models": [
        {
          "name": "qwen3-coder:latest",
          "display_name": "Qwen 3 Coder",
          "max_tokens": 64000,
          "supports_tools": true,
          "keep_alive": "15m",
          "supports_thinking": false,
          "supports_images": false
        }
      ]
    }
  },
```

Release Notes:

- Fixed an issue where Ollama model parameters were not being correctly
overridden by user settings.

Previously, every piece of text in the agent panel was controlled by
`agent_font_size`. Although it is nice to only have one setting to tweak
that, it could be a bit misleading particularly because we use
monospaced and sans-serif fonts for different elements in the panel. Any
editor/textarea in the panel, whehter it is the main message editor or
the previous message editor, uses the buffer font. Therefore, I think it
is reasonable to expect that tweaking `buffer_font_size` would also
change the agent panel's usage of buffer fonts.

With this change, regular buffers and the agent panel's message editor
will always have the same size.

Release Notes:

- agent: Made the agent panel's textarea font size follow the font size
of regular buffers. They're now both controlled by the
`buffer_font_size` setting.

Address an issue where, in Vim mode, clicking past the end of a line
after selecting the entire line would place the cursor on the newline
character instead of the last character of the line, which is
inconsistent with Vim's normal mode expectations.

I believe the root cause was that the cursor’s position was updated to
the end of the line before the mode switch from Visual to Normal, at
which point `DisplayMap.clip_at_line_ends` was still set to `false`. As
a result, the cursor could end up in an invalid position for Normal
mode. The fix ensures that when switching between these two modes, and
if the selection is empty, the selection point is properly clipped,
preventing the cursor from being placed past the end of the line.

Release Notes:

- Fixed issue in Vim mode where switching from any mode to normal mode
could end up with the cursor in the newline character

Nowadays, people don't expect @-mentioning a directory to include the
contents of all files within it. Doing so makes it very likely to
consume an undesirable amount of tokens.

By default, we'll now only include the path of the directory and let the
model decide how much to read via tools. We'll still include the
contents if no tools are available (e.g. "Minimal" profile is selected).

Release Notes:

- Agent Panel: Do not include the content of @-mentioned directories
when tools are available
