Closes #18287

Release Notes:

- Added autocomplete for lsp initialization_options

## Description
This MR adds the following code-changes:
- `initialization_options_schema` to the `LspAdapter` to get JSON
Schema's from the language server
- Adds a post-processing step to inject schema request paths into the
settings schema in `SettingsStore::json_schema`
- Adds an implementation for fetching the schema for rust-analyzer which
fetches it from the binary it is provided with
- Similarly for ruff

## Open Questions(Would be nice to get some advice here)
- Binary Fetching:
- I'm pretty sure the binary fetching is suboptimal. The main problem
here was getting access to the delegate but i figured that out
eventually in a way that i _hope_ should be fine.
- The toolchain and binary options can differ from what the user has
configured potentially leading to mismatches in the autocomplete values
returned(these are probably rarely changed though). I could not really
find a way to fetch these in this context so the provided ones are for
now just `default` values.
- For the trait API it is just provided a binary, since i wanted to use
the potentially cached binary from the CachedLspAdapter. Is that fine
our should the arguments be passed to the LspAdapter such that it can
potentially download the LSP?
- As for those LSPs with JSON schema files in their repositories i can
add the files to zed manually e.g. in
languages/language/initialization_options_schema.json, which could cause
mismatches with the actual binary. Is there a preferred approach for Zed
here also with regards to updating them?

Release Notes:

- Fixed spurious "no checkpoint" error in agent panel

---

## Summary

`update_last_checkpoint` would call `last_user_message()` twice - once
at the start to capture the checkpoint, and again in an async closure
after the checkpoint comparison completed. If a new user message without
a checkpoint was added between these two calls, the second call would
find the new message and fail with "no checkpoint".

## Fix

Capture the user message ID at the start and use `user_message_mut(&id)`
in the async closure to find the specific message.

This PR fixes two issues with regards to markdown codeblocks rendered in
tool call input and output content display:
- the JSON code snippets weren't properly indented
- codeblocks weren't being rendered in unique containers; e.g., if you
hovered one scrollbar, all of them would also be hovered, even though
horizontal scrolling itself worked properly

Here's the end result:


https://github.com/user-attachments/assets/3d6daf64-0f88-4a16-a5a0-94998c1ba7e2

Release Notes:

- agent: Fix scrollbar and JSON indentation for tool call input/output
content's markdown codeblocks.

- Make the buttons capable of changing the editor's content
(incrementing or decrementing the value)
- Make arrow key up and down increment and decrement the editor value
- Tried to apply a bit of DRY here by creating some functions that can
be reused across the buttons and editor given they all essentially do
the same thing (change the value)
- Fixed an issue where the editor would not allow focus to move
elsewhere, making it impossible to open a dropdown, for example, if your
focus was on the number field's editor

Closes https://github.com/zed-industries/zed/issues/43208

This PR essentially unblocks the editable number field. The function
that shapes editor lines was hard-coding text alignment to the left,
meaning that whatever different alignment we'd pass through
`EditorStyles`would be ignored. To solve this, I just added a text align
and align width fields to the line paint function and updated all call
sites keeping the default configuration. Had to also add an
`alignment_offset()` helper to make sure the cursor positioning, the
selection background element, and the click-to-focus functionality were
kept in-sync with the non-left aligned editor.

Then... the big star of the show here is being able to add the `mode`
method to the number field, which uses `TextAlign::Center`, thus making
it work as we designed it to work.

Currently on x11, gpui PopUp windows only rely on the "notification"
type in order to indicate that they should spawn as floating window.
Several window managers (leftwm in my case, but it also seems to be the
case for dwm and ratpoison) do not this property into account thus not
spawning them as float. On the other hand, using Floating instead of
PopUp do make those windows spawn as floating, as these window manager
do take into account the (older) "dialog" type.

The [freedekstop
documentation](https://specifications.freedesktop.org/wm/1.5/ar01s05.html#id-1.6.7)
does seem to suggest that these windows should also have the override
redirect property :
> This property is typically used on override-redirect windows. 

Note that this also disables pretty much all interactions with the
window manager (such as moving the window, resizing etc...)

This fixes an X11 scrolling issue where Zed may jump by a large amount
due to the scroll valuator state not being reset when the window loses
focus. If you Alt-Tab away from Zed, scroll in another application, then
return, the first scroll event in Zed applies the entire accumulated
delta instead of a single step.

The missing FocusOut reset was originally identified in issue #34901.

Resetting scroll positions on FocusOut matches the behavior already
implemented in the XinputLeave handler and prevents this jump.

Closes #34901
Closes #40538

Release Notes:

- Fixed an X11 issue where Alt-Tabbing to another application,
scrolling, and returning to Zed could cause the next scroll event to
jump by a large amount.

I've just enriched the existing tab_stop.rs example for GPUI with a
demonstration of tab_group. I don't think tab groups existed when the
original example was written.

(I didn't understand the behaviour for tab_group from the doccomments
and the example was missing, so I think this is a productive PR)

The failure would happen if the current version of the file was open as
an editor. This happened because the git blob and current version of the
buffer would have the same `ProjectPath`.

The fix was adding a new `DiskState::Historic` variant to represent
buffers that are past versions of a file (usually a snapshot from
version control). Historic buffers don't return a `ProjectPath` because
the file isn't real, thus there isn't and shouldn't be a `ProjectPath`
to it. (At least with the current way we represent a project path)

I also change the display name to use the local OS's path style instead
of being hardcoded to Posix, and cleaned up some code too.

## Problem

When users paste or drag large images into the agent panel, the encoded
payload can exceed upstream provider limits (e.g., Anthropic's 5MB
per-image limit), causing API errors.

## Solution

Enforce a default 5MB limit on encoded PNG bytes in
`LanguageModelImage::from_image`:

1. Apply existing Anthropic dimension limits first (1568px max in either
dimension)
2. Iteratively downscale by ~15% per pass until the encoded PNG is under
5MB
3. Return `None` if the image can't be shrunk within 8 passes
(fail-safe)

The limit is enforced at the `LanguageModelImage` conversion layer,
which is the choke point for all image ingestion paths (agent panel
paste/drag, file mentions, text threads, etc.).

## Future Work

The 5MB limit is a conservative default. Provider-specific limits can be
introduced later by adding a `from_image_with_constraints` API.

## Testing

Added a regression test that:
1. Generates a noisy 4096x4096 PNG (guaranteed >5MB)
2. Converts it via `LanguageModelImage::from_image`
3. Asserts the result is ≤5MB and was actually downscaled

This commit fixes an issue where saving UTF-16 files resulted in UTF-8
bytes due to `encoding_rs` default behavior. It also introduces a
heuristic to detect BOM-less UTF-16 and binary files.

Changes:
- Manually implement UTF-16LE/BE encoding during file save to avoid
implicit UTF-8 conversion.
- Add `analyze_byte_content` to guess UTF-16LE/BE or Binary based on
null byte distribution.
- Prevent loading binary files as text by returning an error when binary
content is detected.

Special thanks to @CrazyboyQCD for pointing out the `encoding_rs`
behavior and providing the fix, and to @ConradIrwin for the suggestion
on the detection heuristic.

Closes #14654

Release Notes:

- (nightly only) Fixed an issue where saving files with UTF-16 encoding
incorrectly wrote them as UTF-8. Also improved detection for binary
files and BOM-less UTF-16.

Closes #ISSUE

It's been a little that we've noticed some flickering and other weird
resizing behavior with text truncation in Zed:


https://github.com/user-attachments/assets/4d5691a3-cd3d-45e0-8b96-74a4e0e273d2


https://github.com/user-attachments/assets/d1d0e587-7676-4da0-8818-f4e50f0e294e

Initially, we suspected this could be due to how we calculate the length
of a line to insert truncation, which is based first on the length of
each individual character, and then second goes through a pass
calculating the line length as a whole. This could cause mismatch and
culminate in our bug.

However, even though that felt like a reasonable suspicion, I realized
something rather simple at some point: the `truncate` and
`truncate_start` methods in the `Label` didn't use `whitespace_nowrap`.
If you take Tailwind as an example, their `truncate` utility class takes
`overflow: hidden; text-overflow: ellipsis; white-space: nowrap;`. This
pointed out to a potential bug with `whitespace_nowrap` where that was
blocking truncation entirely, even though that's technically part of
what's necessary to truncate as you don't want text that will be
truncated to wrap.

Ultimately, what was happening was that the text element was caching its
layout based on its `wrap_width` but not considering its
`truncate_width`. The truncate width is essentially the new definitive
width of the text based on the available space, which was never being
computed. So the fix here was to add `truncate_width.is_none()` to the
cache validation check, so that it only uses the cached text element
size _if the truncation width is untouched_. But if that changes, we
need to account for the new width. Then, in the Label component, we
added `min_w_0` to allow the label div to shrink below its original
size, and finally, we added `whitespace_nowrap()` as the cache check
fundamentally fixed that method's problem.

In a future PR, we can basically remove the `single_line()` label method
because: 1) whenever you want a single label, you most likely want it to
truncate, and 2) most instances of `truncate` are already followed by
`single_line` in Zed today, so we can cut that part.

Result is no flickering with truncated labels!
