Cherry-picked Fix panic when deleting an empty line after a deleted hunk
(#24255)

Release Notes:

- Fix a panic when deleting text after a deletion hunk

Co-authored-by: Cole Miller <cole@zed.dev>

Closes https://github.com/zed-industries/zed/issues/10192 , again.

Release Notes:

- Fixed multiple save modals appearing when app is being closed multiple
times

Release Notes:

- Fixed some modifier changed events not being present on Linux X11.
This affected things like the project search palette, where holding ctrl
would not cause the split options to appear.

We think this could fix issues around view invalidation during focus
handling.

I want to run CI on this and see.

Release Notes:

- N/A

Certain themes define the `created` and `deleted` status colors, but not
`created_background` and `deleted_background`. Previously, Zed would use
`created` and `deleted` colors, and apply a hard-coded opacity change,
but *not* use `created_background` and `deleted_background`, but that
behavior was inadvertently changed in
https://github.com/zed-industries/zed/pull/22994.

This PR restores the old behavior as a fallback. If a theme defines a
status color, but not the corresponding background color, we'll use a
75% transparent version of the foreground color as a fallback.

Release Notes:

- Fixed an issue in certain themes where diffs would render with the
wrong red and green colors for deletions and insertions.

This PR makes it so when you install an extension with icon themes it
will deploy the icon theme selector filtered down to the newly-installed
icon themes.

This is similar to what we do when installing an extension with themes.

Because we can only have one picker open at a time, when installing an
extension that has _both_ themes and icon themes, the theme selector
will take precedence.

Release Notes:

- N/A

This PR adds support for icon themes.

Closes https://github.com/zed-industries/zed/issues/8843.

Here is Zed with Material Icons:

/>

### Extensions

Extensions can provide icon themes as well as the icons used in those
themes.

Icon themes are defined as JSON files in the `icon_themes` directory,
and icons included in the `icons` directory will be packaged up with the
extension.

All icon paths within an icon theme are interpreted relative to the root
of the extension.

See the [Material Icon
Theme](https://github.com/zed-extensions/material-icon-theme) extension
for an example.

Release Notes:

- Added support for icon themes.
  - Extensions can now provide icon themes.
- Use the `icon theme selector: toggle` action to switch between
installed icon themes.

This PR fixes an issue where we weren't properly resolving directory and
chevron icons from icon themes the way we were for file icons.

We need to interpret the icon paths as relative to the extension
directory.

Release Notes:

- N/A

This PR adds an icon theme selector for switching between icon themes:

Sorry to dump an unsolicited PR for a hot feature! I'm sure someone else
was taking a look at this.

I noticed that token counting was disabled and I was getting error logs
of the form `[2025-01-31T22:59:01-05:00 ERROR assistant_context_editor]
No tokenizer found for model o3-mini` when using the new model. To fix
the issue, this PR registers the `gpt-4` tokenizer for this model.

Release Notes:

- openai: Fixed Assistant token counts for `o3-mini` models

- Closes https://github.com/zed-industries/zed/issues/23764

Certain models do not include `quantization` parameter from lm studio rest API.

Forgot to run default.json through prettier in #24051. Oops.

Make sure that inline completions (Copilot, etc) are disabled for more secret globs (matches `private_files`)

Release Notes:

- Add support for OpenAI o3-mini

After the user confirmation, only the current instance of the
completions provider had the answer stored.

In this PR, the changes are propagated by having each provider have an
`Entity<choice>`, and having a lookup map with one `Entity<choice>` for
each worktree that `Zeta` has seen.

Release Notes:

- N/A

@nathansobo and I paired on revising this menu, including adding the
"Predict Edits at Cursor" menu item (to make the keyboard shortcut more
discoverable; clicking it makes the inline edits show up, as shown in
the second screenshot) and switching from "Hide/Show" language to
checkboxes.

/>

We also switched to use `SharedString` in more places, where it made
more sense.

@danilo-leal This isn't necessarily *exactly* what we want, but we were
pairing and decided to get it in a state where we can actually try it
out and tweak from here.

https://github.com/zed-industries/zed/pull/23256
* Fixes project panel items drag and drop not working after selection
overhaul even earlier: now, all marked items are added to terminal on
drag and drop

Release Notes:

- Fixed terminal drag and drop, including project panel items

Previously we returned an error when the interpolation failed in
`process_completion_response`.
However, it is not an error when interpolation returns `None`. That just
means that the predicted edits can be discarded, because the user typed
something that is not a subset of what the model predicted OR if the
model responds with a no-op.
```
2025-01-29T09:44:30.221135+01:00 [ERROR] zeta prediction failed

Caused by:
    Interpolated edits are empty

Release Notes:

- N/A

Release Notes:

- Fixed incorrect action names in TextMate keymap.

Required using a global `LazyLock<Mutex<AppNotifications>>` instead of a
context global because settings errors first occur before initialization
of the notifications global.

Release Notes:

- Errors in settings file are now reported in UI on startup.

I'm moving forward on this - we can revert if it ends up being a bad
move.

# Add AnyBrackets text object for Vim mode

## Overview
This PR introduces a new text object `AnyBrackets` that allows
operations on the closest matching pair of brackets, regardless of the
bracket type. This enhances the editing experience by reducing the need
to identify specific bracket types before performing text operations.

By default, this feature is NOT mapped to any key in vim.json. However,
it can be enabled manually, and the recommended key for mapping is b:

If you want to add it to your zed keymap config you need to add the
following config:
```json
{
	"context": "vim_operator == a || vim_operator == i || vim_operator == cs",
	"bindings": {
		"b": "vim::AnyBrackets"
	}
}
```

## Features
- New text object that works with parentheses `()`, square brackets
`[]`, curly braces `{}`, they are also know as round brackets, square
brackets and curly brackets in english.
- Automatically finds the closest matching pair of any bracket type
- Works with all standard Vim operators (delete, change, yank)
- Supports both "inside" and "around" variants (`i` and `a`)

## Usage Examples
```vim
# Delete inside the closest brackets
di(  # Works on (), [] or {} depending on which is closest

# Change around the closest brackets
ca[  # Works on (), [] or {}  depending on which is closest

# Visual select inside the closest brackets
vi{  # Works on (), [] or {}  depending on which is closest
```

# References:
- Based on the popular plugin https://github.com/echasnovski/mini.ai

# Important Notes
This PR also fixes a bug with nested quotes on AnyQuotes, now it works
fine with any type of quotes or brackets.
Please take a look at the new tests to understand the expected behavior.

Release Notes:

- vim: Add `ab`/`ib` "AnyBrackets" text objects that are the smallest of
`a(`, `a[` or `a{` or `i(`, `i[` or `i{`
- vim: Fix aq/iq "AnyQuotes" text objects when they are nested

This fixes an edge case when two hunk controls button groups were
visible (due to having text cursor on one hunk, and mouse cursor on the
other). In that situation, the mouse states for the two button groups
would mirror.

Release Notes:

- N/A
