Cherry-picked Fix panic dragging tabs multiple positions to the right
(#32305)

Closes https://github.com/zed-industries/zed/issues/32303

Release Notes:

- Fixed a panic that occurred when dragging tabs multiple positions to
the right (preview only)

Co-authored-by: Joseph T. Lyons <JosephTLyons@gmail.com>

Closes #32205

The issue was that in some places the end of the replacement range used
anchors with `Bias::Left` instead of `Bias::Right`. Before #31872
completions were recomputed on every change and so the anchor bias
didn't matter. After that change, the end anchor didn't move as the
user's typing. Changing it to `Bias::Right` to "stick" to the character
to the right of the cursor fixes this.

Also fixes slash command arguments to now have `is_incomplete: true`,
since some of the argument providers do limited fuzzy matching.

Release Notes:

- Fixed slash command completions in agent text threads to replace the
user's query text (Preview Only)

This was a regression with my recent fixes to pinned tabs. Dragging a
pinned tab left in the pinned region would still update the pinned tab
count, which would later cause an out-of-bounds later when it used that
value to index into a vec.

Release Notes:

- Fixed a bug where if the last tab was a pinned tab and it was dragged
to the right, resulting in a no-op, it would become unpinned
- Fixed a bug where a pinned tab dragged just to the right of the end of
the pinned tab region would become unpinned
- Fixed a bug where dragging a pinned tab from one pane to another
pane's pinned region could result in an existing pinned tab becoming
unpinned when `max_tabs` was reached
- Fixed a bug where moving an unpinned tab to the left, just to the end
of the pinned region, would cause the pinned tabs to become unpinned.

Fix 1: A pinned tab dragged into a new split should remain pinned


https://github.com/user-attachments/assets/608a7e10-4ccb-4219-ba81-624298c960b0

Fix 2: Moving a pinned tab from one pane to another should not cause
other pinned tabs to be unpinned


https://github.com/user-attachments/assets/ccc05913-591d-4a43-85bb-3a7164a4d6a8

I also added tests for moving both pinned tabs and unpinned tabs into
existing panes, both into the "pinned" region and the "unpinned" region.

Release Notes:

- Fixed a bug where dragging a pinned tab into a new split would lose
its pinned tab state.
- Fixed a bug where pinned tabs in one pane could be lost when moving
one of the pinned tabs to another pane.

Hi, this pull request adds `sorbet` and `steep` to the list of available
language servers for the Ruby language in order to prepare default Ruby
language settings for these LS. Both language servers are disabled by
default. We plan to add both in #104 and #102. Thanks!

Release Notes:

Removes the load_model trait method and its implementations in Ollama
and LM Studio providers, along with associated preload_model functions
and unused imports.

When `<old_text>` points to more than one location in a file, we used to
edit the first match, confusing the agent along the way. Now we will
return an error, asking to expand `<old_text>` selection.

Closes #ISSUE

Release Notes:

- agent: Fixed incorrect file edits when edit locations are ambiguous

Follow-up of https://github.com/zed-industries/zed/pull/30707

The old code does something odd, re-accessing essentially the same
adapter-server pair for every language server initialized; but that was
done before for "incorrect", non-reused worktree_id hence never resulted
in external worktrees' files registration in this code path.

Release Notes:

- Fixed certain external worktrees' files sometimes not registered with
language servers

It seems that there was a regression. `build_config` no longer has an
`OUT_DIR` in it.
On way to mitigate it is to stop relying on it and just use `cwd` as dir
for the test binary to be placed in.

Modify the `replace_and_mark_text_in_range` method in the `Editor` to
keep the cursor at the start of the preedit range during IME
composition. Previously, the cursor would move to the end of the preedit
text with each update, causing the IME candidate box to shift (e.g.,
when typing pinyin with Fcitx5 on Wayland). This change ensures the
cursor and candidate box remain fixed until the composition is
committed, improving the IME experience.

Closes #14496.

In https://github.com/zed-industries/zed/pull/31976, we modified the
highlighting behavior for entries when certain entries or paths are
being dragged over them. Instead of relying on marked entries for
highlighting, we introduced the `highlight_entry_id` parameter, which
determines which entry and its children should be highlighted when an
item is being dragged over it.

The rationale behind that is that we can now utilize marked entries for
various other functions, such as:

1. When dragging multiple items, we use marked entried to show which
items are being dragged. (This is already covered because to drag
multiple items, you need to use marked entries.)
2. When dragging a single item, set that item to marked entries. (This
PR)

Prep for https://github.com/zed-industries/zed/pull/32040

Currently, there’s no way to modify the cursor style of the active drag
state after dragging begins. However, there are scenarios where we might
want to change the cursor style, such as pressing a modifier key while
dragging. This PR introduces an API to update and read the current
active drag state cursor.

Fixes #27601

Zed’s current method of loading environment variables from the login
shell has two issues:
1. Some shells—​fish in particular—​​write specific escape characters to
`stdout` right before they exit. When this happens, the tail end of the
last environment variable printed by `/usr/bin/env` becomes corrupted.
2. If a multi-line value contains an equals sign, that line is
mis-parsed as a separate name-value pair.

This PR addresses those problems by:
1. Redirecting the shell command's `stdout` directly to a temporary
file, eliminating any side effects caused by the shell itself.
2. Replacing `/usr/bin/env` with `sh -c 'export -p'`, which removes
ambiguity when handling multi-line values.

Additional changes:
- Correctly set the arguments used to launch a login shell under `csh`
or `tcsh`.
- Deduplicate code by sharing the implementation that loads environment
variables on first run with the logic that reloads them for a project.

`"use_system_path_prompts": false` is needed in settings for these to

Closes: https://github.com/rzukic/zed-latex/issues/77 

## Default formatter: `latexindent`
Before, formatting was delegated to the language server, which just ran
a `latexindent` executable. There was no benefit to running it through
the language server over running it as an "external" formatter in zed.
In fact this was an issue because there was no way to provide an
explicit path for the executable (causing above extension issue). Having
the default settings configure the formatter directly gives more control
to user and removes the number of indirections making it clearer how to
tweak things like the executable path, or extra CLI args, etc...

## Alternative: `prettier`
Default settings have also been added to allow prettier as the formatter
(by just setting `"formatter": "prettier"` in the "LaTeX" language
settings). This was not possible before because an extra line needed to
be added to the `prettier` crate (similarly to what was done for
https://github.com/zed-industries/zed/issues/19024) to find the plugin
correctly.
> [!NOTE]
> The `prettier-plugin-latex` node module also contained a
`dist/standalone.js` but using that instead of
`dist/prettier-plugin-latex.js` gave an error, and indeed the latter
worked as intended (along with its questionable choices for formatting).

Release Notes:

- LaTeX: added default `latexindent` formatter settings without relying
on `texlab`, as well as allowing `prettier` to be chosen for formatting

This PR adds highlighting on the containing folder which would be the
target of the drop operation. It only highlights those directories where
actual drop is possible, i.e. same directory where drag started is not
highlighted.

- [x] Tests


https://github.com/user-attachments/assets/46528467-e07a-4574-a8d5-beab25e70162

Release Notes:

- Improved project panel to show a highlight on the containing folder
which would be the target of the drop operation.

This PR introduces the "Reject All" and "Accept All" buttons in the
panel's edit bar, which appears as soon as the agent starts editing a
file. I'm also adding here a new method to the thread called
`has_pending_edit_tool_uses`, which is a more specific way of knowing,
in comparison to the `is_generating` method, whether or not the
reject/accept all actions can be triggered.

Previously, without this new method, you'd be waiting for the whole
generation to end (e.g., the agent would be generating markdown with
things like change summary) to be able to click those buttons, when the
edit was already there, ready for you. It always felt like waiting for
the whole thing was unnecessary when you really wanted to just wait for
the _edits_ to be done, as so to avoid any potential conflicting state.

These started to be used more recently, so we should also support them.

Release Notes:

- agent: Added support for `AGENT.md` and `AGENTS.md` as rules file
names.

Just polishing up a bit the Rules Library design. I think the most
confusing part here was the icon that was being used to tag a rule as
default; I've heard feedback more than once saying that was confusing,
so I'm now switching to a rather standard star icon, which I'd assume is
well-understood as a "favoriting" affordance.
