Release Notes:

- Added channel reordering for administrators (use `cmd-up` and
`cmd-down` on macOS or `ctrl-up` `ctrl-down` on Linux to move channels
up or down within their parent)

## Summary

This PR introduces the ability for channel administrators to reorder
channels within their parent context, providing better organizational
control over channel hierarchies. Users can now move channels up or down
relative to their siblings using keyboard shortcuts.

## Problem

Previously, channels were displayed in alphabetical order with no way to
customize their arrangement. This made it difficult for teams to
organize channels in a logical order that reflected their workflow or
importance, forcing users to prefix channel names with numbers or
special characters as a workaround.

## Solution

The implementation adds a persistent `channel_order` field to channels
that determines their display order within their parent. Channels with
the same parent are sorted by this field rather than alphabetically.

## Implementation Details

### Database Schema

Added a new column and index to support efficient ordering:

```sql
-- crates/collab/migrations/20250530175450_add_channel_order.sql
ALTER TABLE channels ADD COLUMN channel_order INTEGER NOT NULL DEFAULT 1;

CREATE INDEX CONCURRENTLY "index_channels_on_parent_path_and_order" ON "channels" ("parent_path", "channel_order");
```

### RPC Protocol

Extended the channel proto with ordering support:

```proto
// crates/proto/proto/channel.proto
message Channel {
    uint64 id = 1;
    string name = 2;
    ChannelVisibility visibility = 3;
    int32 channel_order = 4;
    repeated uint64 parent_path = 5;
}

message ReorderChannel {
    uint64 channel_id = 1;
    enum Direction {
        Up = 0;
        Down = 1;
    }
    Direction direction = 2;
}
```

### Server-side Logic

The reordering is handled by swapping `channel_order` values between
adjacent channels:

```rust
// crates/collab/src/db/queries/channels.rs
pub async fn reorder_channel(
    &self,
    channel_id: ChannelId,
    direction: proto::reorder_channel::Direction,
    user_id: UserId,
) -> Result<Vec<Channel>> {
    // Find the sibling channel to swap with
    let sibling_channel = match direction {
        proto::reorder_channel::Direction::Up => {
            // Find channel with highest order less than current
            channel::Entity::find()
                .filter(
                    channel::Column::ParentPath
                        .eq(&channel.parent_path)
                        .and(channel::Column::ChannelOrder.lt(channel.channel_order)),
                )
                .order_by_desc(channel::Column::ChannelOrder)
                .one(&*tx)
                .await?
        }
        // Similar logic for Down...
    };
    
    // Swap the channel_order values
    let temp_order = channel.channel_order;
    channel.channel_order = sibling_channel.channel_order;
    sibling_channel.channel_order = temp_order;
}
```

### Client-side Sorting

Optimized the sorting algorithm to avoid O(n²) complexity:

```rust
// crates/collab/src/db/queries/channels.rs
// Pre-compute sort keys for efficient O(n log n) sorting
let mut channels_with_keys: Vec<(Vec<i32>, Channel)> = channels
    .into_iter()
    .map(|channel| {
        let mut sort_key = Vec::with_capacity(channel.parent_path.len() + 1);
        
        // Build sort key from parent path orders
        for parent_id in &channel.parent_path {
            sort_key.push(channel_order_map.get(parent_id).copied().unwrap_or(i32::MAX));
        }
        sort_key.push(channel.channel_order);
        
        (sort_key, channel)
    })
    .collect();

channels_with_keys.sort_by(|a, b| a.0.cmp(&b.0));
```

### User Interface

Added keyboard shortcuts and proper context handling:

```json
// assets/keymaps/default-macos.json
{
  "context": "CollabPanel && not_editing",
  "bindings": {
    "cmd-up": "collab_panel::MoveChannelUp",
    "cmd-down": "collab_panel::MoveChannelDown"
  }
}
```

The CollabPanel now properly sets context to distinguish between editing
and navigation modes:

```rust
// crates/collab_ui/src/collab_panel.rs
fn dispatch_context(&self, window: &Window, cx: &Context<Self>) -> KeyContext {
    let mut dispatch_context = KeyContext::new_with_defaults();
    dispatch_context.add("CollabPanel");
    dispatch_context.add("menu");
    
    let identifier = if self.channel_name_editor.focus_handle(cx).is_focused(window) {
        "editing"
    } else {
        "not_editing"
    };
    
    dispatch_context.add(identifier);
    dispatch_context
}
```

## Testing

Comprehensive tests were added to verify:
- Basic reordering functionality (up/down movement)
- Boundary conditions (first/last channels)
- Permission checks (non-admins cannot reorder)
- Ordering persistence across server restarts
- Correct broadcasting of changes to channel members

## Migration Strategy

Existing channels are assigned initial `channel_order` values based on
their current alphabetical sorting to maintain the familiar order users
expect:

```sql
UPDATE channels
SET channel_order = (
    SELECT ROW_NUMBER() OVER (
        PARTITION BY parent_path
        ORDER BY name, id
    )
    FROM channels c2
    WHERE c2.id = channels.id
);
```

## Future Enhancements

While this PR provides basic reordering functionality, potential future
improvements could include:
- Drag-and-drop reordering in the UI
- Bulk reordering operations
- Custom sorting strategies (by activity, creation date, etc.)

## Checklist

- [x] Database migration included
- [x] Tests added for new functionality
- [x] Keybindings work on macOS and Linux
- [x] Permissions properly enforced
- [x] Error handling implemented throughout
- [x] Manual testing completed
- [x] Documentation updated

Follow up of #29872

Release Notes:

- Make `alt-left` and `alt-right` skip punctuation on Mac OS to respect
the Mac default behaviour. When pressing alt-left and the first
character is a punctuation character like a dot, this character should
be skipped. For example: `hello.|` goes to `|hello.`

This change makes the editor feels much snappier, it now follows the
same behaviour as VSCode and any other Mac OS native application.

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)

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.

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.

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.

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.
