Consolidates configuration error handling by moving the error type and
logic from assistant_context_editor to language_model::registry.

The registry now provides a single method to check for configuration
errors, making the error handling more consistent across the agent panel
and context editor.

This also now checks if the issue is that we don't have any providers,
or if we just can't find the model.

Previously, an incorrect model name showed up as having no providers,
which is very confusing.

If the proxy URL is in the form of `example.com` instead of a raw IP
address, and `example.com` isn't a well-known domain, then the default
URL resolution can fail.

The test setup:

A Linux machine runs a CoreDNS server with a custom entry: `10.254.7.38
example.com`. On a Windows machine, if the proxy URL is set to
`example.com`, the resolved address does **not** end up being
`10.254.7.38`.

Using `hickory_resolver` for more advanced DNS resolution fixes this
issue.


Release Notes:

- Fixed proxy URL resolution when using custom DNS entries.

Formatted via format-on-save in Zed with prettier version 3.5.3

Closes #4385

Allow action `project_panel::CollapseAllEntries` to trigger from
workspace context without focusing the project panel.

Release Notes:

- Added a way to collapse all entries in the Project Panel without
having to focus it. This can be done by using the
`project_panel::CollapseAllEntries` action.

Release Notes:

- N/A

Mistake in #31863 where the stored log entries no longer had a format
that could simply have `\n` added after each entry.

Also fixes a potential crash in the long line folding logic if unicode
was in the logs - introduced in #22996.

Also updates the log line truncation logic to never exceed the
pre-allocated capacity

Release Notes:

Release Notes:

- Added initial support for both `z l` and `z h` in vim mode

These changes relate to #17219 but don't yet close the issue, as this
Pull Request is simply adding support for horizontal scrolling in vim
mode and actually moving the cursor to the correct column in the current
row will be handled in a different Pull Request.

Some notes on these changes:

- 2 new default keybindings added to vim's keymap
    - `z l` which triggers the new `vim::ColumnRight` action
    - `z h` which triggers the new `vim::ColumnLeft` action
- Introduced a new `ScrollAmount` variant, `ScrollAmount::Column(f32)`
to represent horizontal scrolling
- Replaced usage of `em_width` with `em_advance` to actually scroll by
the width of the cursor, instead of the width of the character

Release Notes:

- Improved auto-complete suggestions for Tailwind classes.

Release Notes:

- agent: Clicking on header of an edit file card now takes you to the
first modified hunk

I think we mistakenly added an early return for the review multibuffer
button if `has_pending_edit_tool_uses` is true. It is totally fine _to
access_ the review multibuffer while that's happening. It's another
thing to _accept and reject_ changes while they're still ongoing!

Release Notes:

- agent: Fixed access to the review multibuffer from the agent panel.

In this PR I want to improve the UI of the project panel's files tree.
Currently, the project panel renders an extra gap between file icons and
the file name, making it visually unpleasant. The changes in the PR
remove the gap, bringing the labels closer to their icon:

_Before/After_

<img width="647" alt="zed-before-after"
src="https://github.com/user-attachments/assets/d815c075-f1f8-4a77-a3b3-d1275988a5dc"
/>

Also, this extra gap between the icon and the label seems inconsistent
with how other similar components, which are based on the `ListItem`,
are used.

Release Notes:

- Fixed an extra gap between the file icon and the file name label in
the project panel.

This is reverting a change from #32071 which caused agent following to
stop after the file was edited.

This will reintroduce the behavior that the keyboard shortcuts don't
work until the model is done generating, but we will revisit that
afterwards.

Closes #32592
Follow-up to #31965 

This PR fixes the cursor style flickering on Linux systems. The issue
arose since the window cursor style was not reused anymore for
subsequent frames after the changes in #31965. This works on MacOS for
hiding cursors, since they are hidden until the next mouse movement
occurs, which is not the case for other systems.

This PR re-adds this whilst keeping the fixes applied in #31965. We now
determine the first cursor style that is hovered and continue searching
for a cursor style that should be applied globally. If one to apply for
the whole window is found, we return that cursor style early instead.

Alternatively, we could store window cursor style request in a vector
similar to normal cursor styles. That would require more memory in
exchange for fewer checks which cursor style to apply. I preferred the
approach here, though, but can change this should the other method be
preferred.

CC @smitbarmase since you assigned yourself that issue.

Release Notes:

- Fixed an issue where the cursor would flicker whilst typing.

Release Notes:

- openai: Remove support for deprecated o1-preview and o1-mini models 
- openai: Support streaming for o1 model

I also enabled the `Restart` action even for sessions that don't support
restarting because we have a restart fallback now.

Closes #31408

Release Notes:

- Fix bug where a debugger session would never be shutdown on a failed
restart attempt

Closes #32217

This fixes a bug introduced in #32579 where the code runner menu would

`serialized.centered_layout`
- Ensures the centered layout state persists across project switches

Closes #21860

Release Notes:

- Added `ch_width` and `ch_advance` function alongside their `em_*`
counterparts
- Use `ch_*` version to calculate gutter layouts
- Update a stale comment from changes in #31959

The ch units refer to the width of the number `0` whereas em is the
width of `m` and the actual font size (e.g. 16px means 16 px width of
`m`).

This change has no effect for monospaced fonts but can be drastic for
proportional ones as seen below for "Zed Plex Sans" with a
`"min_line_number_width" = 4`.

these lists mutually exclusive.

Release Notes:

Fixes #31699

Eventually we might want to merge the lists and deduplicate based on the
command and args that it's running. For now we'll just use the presence
of _any_ worktree local zed debug tasks to disable all VSCode ones.

Release Notes:

- N/A

- Add `300ms` delay for it to consider it as selection drag instead of
an attempt to make a new selection.
- Add cursor icon while dragging the selection.

This is same as what chromium does:
https://chromium.googlesource.com/chromium/blink/+/master/Source/core/input/EventHandler.cpp#142

Release Notes:

- Fixed issue where you accidentally end up dragging the selection where
intent was to make a new one instead. To drag selection now, you need to
hold just a little longer before dragging.

Closes #32577

Release Notes:

- Fixed debugger malfunctioning when using ZED_WORKTREE_ROOT env
variable in multi-worktree workspaces.

Send `runtimeExecutable` and `runtimeArgs` instead of `program` and
`args` to avoid the DAP implicitly wrapping the command in `node`.

This means that putting `pnpm vitest <file>` as the command in the
launch modal will work, as will this in debug.json:

```
[
  {
    "adapter": "JavaScript",
    "type": "pwa-node",
    "label": "Label",
    "request": "launch",
    "program": "pnpm",
    "args": ["vitest", "<file>"],
    "cwd": "/Users/name/project"
  }
]
```


Release Notes:

- Debugger Beta: made it possible to use commands like `pnpm
<subcommand> <args>` in the launch modal and debug.json

Now if you click the triangle you get runnables, if you click the
lightning bolt you get code actions, if you trigger the code actions
menu with the mouse/keyboard you still get both.

Release Notes:

- Fixed the run/code actions menu to not duplicate content when opened
from the respective icons.
