- #44407

This PR further improves performance for regex hyperlink finding by
eliminating unnecessary regex matching. Currently, we repeatedly search
for matches from the start of the line until the match contains the
hovered point. This is only required to support custom regexes which
match strings containing spaces, with multiple matches on a single line.
This isn't actually a useful scenario, and is no longer supported. This
PR changes to only search twice, the first match starting from the start
of the line, and the hovered word (space-delimited). The most dramatic
improvement is for long lines with many words.

In addition to the above changes, this PR:
- Adds test for the scenarios from #44407 and #44510 
- Simplifies the logic added in #44407

Performance measurements

For the scenario from #44407, this improves the perf test's iteration
time from 1.22ms to 0.47ms.

## Summary

Addresses #16965

This PR adds support for **opening and saving** files with legacy
encodings (non-UTF-8).
Previously, Zed failed to open files encoded in Shift-JIS, EUC-JP, Big5,
etc., displaying a "Could not open file" error screen. This PR
implements automatic encoding detection upon opening and ensures the
original encoding is preserved when saving.

## Implementation Details

1.  **Worktree (Loading)**:
* Updated `load_file` to use `chardetng` for automatic encoding
detection.
* Files are decoded to UTF-8 internal strings for editing, while
preserving the detected `Encoding` metadata.
2.  **Language / Buffer**:
* Added an `encoding` field to the `Buffer` struct to store the detected
encoding.
3.  **Worktree (Saving)**:
    * Updated `write_file` to accept the stored encoding.
    * **Performance Optimization**:
* **UTF-8 Path**: Uses the existing optimized `fs.save` (streaming
chunks directly from Rope), ensuring no performance regression for the
vast majority of files.
* **Legacy Encoding Path**: Implemented a fallback that converts the
Rope to a contiguous `String/Bytes` in memory, re-encodes it to the
target format (e.g., Shift-JIS), and writes it to disk.
* *Note*: This fallback involves memory allocation, but it is necessary
to support legacy encodings without refactoring the `fs` crate's
streaming interfaces.

## Changes

- `crates/worktree`:
    - Add dependencies: `encoding_rs`, `chardetng`.
    - Update `load_file` to detect encoding and decode content.
    - Update `write_file` to handle re-encoding on save.
- `crates/language`: Add `encoding` field and accessors to `Buffer`.
- `crates/project`: Pass encoding information between Worktree and
Buffer.
- `crates/vim`: Update `:w` command to use the new `write_file`
signature.

## Verification

I validated this manually using a Rust script to generate test files
with various encodings.

**Results:**

* ✅ **Success (Opened & Saved correctly):**
    * **Japanese:** `Shift-JIS` (CP932), `EUC-JP`, `ISO-2022-JP`
    * **Chinese:** `Big5` (Traditional), `GBK/GB2312` (Simplified)
* **Western/Unicode:** `Windows-1252` (CP1252), `UTF-16LE`, `UTF-16BE`
* ⚠️ **limitations (Detection accuracy):**
* Some specific encodings like `KOI8-R` or generic `Latin1` (ISO-8859-1)
may partially display replacement characters (`?`) depending on the file
content length. This is a known limitation of the heuristic detection
library (`chardetng`) rather than the saving logic.


Release Notes:

- Added support for opening and saving files with legacy encodings
(Shift-JIS, Big5, etc.)

Closes #44715

Release Notes:

- Fixed git tree view folders don't open when file inside is selected

I could not find any related issue, but at least I want to use the git
panel like this :)

Being used to `lazygit`, this PR makes navigation of the git panel more
similar to the CLI tool.

Instead of selecting -> enter'ing for skimming each file, I just want to
move between the files in the git panel and have the diff multibuffer
advance to the appropriate file. This also adheres to the behavior of
the outline panel, which I like better.

If the multibuffer is not active, it behaves same as before (just
selecting the file in the panel, nothing else).

I did not modify existing `menu::Select*` actions in case anybody still
prefers previous behavior.

Release Notes:

- Improved navigation of the git panel, by advancing the "Uncommitted
Changes" multibuffer to the current selected file. To restore the old
behavior, you can bind `up` and `down` to `menu::SelectPrevious` and
`menu::SelectNext` under the `GitPanel` context in your keymap.

Closes #ISSUE

Problem:

- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.

Fix:

- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

- is this URI scheme appropriate? it was the first one i thought of, but
wondering if `?ref=<some sha>` might make more sense – the git/commit
namespace was also an equally arbitrary choice

Previously, the list of edit files had a double axis scroll issue

scroll horizontally, causing a bad UX. The horizontal scroll intention
was so that you could see the whole path, but I've included it in the
tooltip in case it becomes obscured due to a small panel width.

Fixes an issue where we would update the imports after a file rename in
TypeScript, but those changes wouldn't surface anywhere until those
buffers were manually opened
(https://github.com/zed-industries/zed/issues/35930#issuecomment-3366852945).
In https://github.com/zed-industries/zed/pull/36681 we already added
support for opening a multibuffer with edits, but vtsls has a different
flow for renames.

Release Notes:

- Files with updated imports now open in a multibuffer when renaming or
moving TypeScript or JavaScript files

Closes #35930

When a TypeScript file is renamed or moved, vtsls can automatically
update the imports in other files. It pops up a message with the option
to always automatically update imports. This choice would previously
only be remembered for the current session and would pop up again after
a restart.

Now we persist that choice to the vtsls LSP settings in Zed, so that it
remembers across editor sessions.

Release Notes:

- When renaming a TypeScript or JavaScript file, the selected option to
automatically update imports will now be remembered across editor
sessions.

Addresses some tasks in #43969. Namely adding TailwindCSS documentation
for the following languages: HTML, JavaScript and Typescript.

**Some Notes**
- Maybe the additional information in the HTML section is unnecessary,
unsure open to suggestions.
- I tried utilizing capturing groups with alternatives like
`\\.(add|remove|toggle|contains)` but this didn't seem to work, so I was
forced to use multiple lines.

Closes #33018

### Problem

When opening a `PopoverMenu` or `RightClickMenu`, the pane's tab bar
buttons would flicker (disappear for a couple frames then reappear).
This happened because:

1. The menu is created and `window.focus()` was called immediately
2. However, menus are rendered using `deferred()`, so their focus
handles aren't connected in the dispatch tree until after the deferred
draw callback runs
3. When the pane checks `has_focus()`, it calls `contains_focused()`
which walks up the focus hierarchy — but the menu's focus handle isn't
linked yet
4. `has_focus()` returns false → tab bar buttons disappear
5. Next frame, the menu is rendered and linked → `has_focus()` returns
true → buttons reappear

### Solution

Delay the focus transfer by 2 frames using nested `on_next_frame()`
calls before focusing the menu.

**Why 2 frames instead of 1?**

The frame lifecycle in GPUI runs `next_frame_callbacks` BEFORE `draw()`:

```
on_request_frame:
  1. Run next_frame_callbacks
  2. window.draw()  ← menu rendered here via deferred()
  3. Present
```

So:
- **Frame 1**: First `on_next_frame` callback runs, queues second
callback. Then `draw()` renders the menu and connects its focus handle
to the dispatch tree.
- **Frame 2**: Second `on_next_frame` callback runs and focuses the
menu. Now the focus handle is connected (from Frame 1's draw), so
`contains_focused()` returns true.

With only 1 frame, the focus would happen BEFORE `draw()`, when the
menu's focus handle isn't connected yet.

This follows the same pattern established in b709996ec6 which fixed the
identical issue for the editor's `MouseContextMenu`.

Closes #ISSUE

This PR is rather a nice to have change than anything critical, so
review priority should remain low.

Switch to using `semver::Version` for representing node binary and npm
package versions. This is in an effort to root out implicit behavior and
improve type safety when interacting with the `node_runtime` crate by
catching invalid versions where they appear. Currently Zed may
implicitly assume the current version is correct, or always install the
newest version when a invalid version is passed. `semver::Version` also
doesn't require the heap, which is probably more of a fun fact than
anything useful.

`npm_install_packages` still takes versions as a `&str`, because
`latest` can be used to fetch the latest version on npm. This could
likely be made into an enum as well, but would make the PR even larger.

I tested changes with some node based language servers and external
agents, which all worked fine. It would be nice to have some e2e tests
for node. To be safe I'd put it on nightly after a Wednesday release.

Before this change, white space would be trimmed from word diff ranges.
Users found this behavior confusing, so we're changing it to be more
inline with how GitHub treats whitespace in their word diffs.

Release Notes:

- git: Word diffs won't filter out pure whitespace diffs now

Both `test_miniquotes_object` and `test_minibrackets_object` rely on
tree-sitter parsing for `MultiBufferSnapshot.bracket_ranges` to find
quote/bracket pairs. The `VimTestContext.set_state` call eventually
triggers async tree-sitter parsing, but `run_until_parked` doesn't
guarantee parsing completion.

We suspect this is what might be causing the flakiness on Windows, as
the syntax might not yet be parsed when the
`VimTestContext.simulate_keystrokes` call is made, so there's no bracket
pairs returned.

This commit adds an explicit await call on `Bufffer.parsing_idle` after
each `VimTestContext.set_state` call, to ensure tree-sitter parsing
completes before simulating keystrokes.

Release Notes:

- N/A

Obviously this doesn't do too much without having an actual windows

Closes #45033 

This bug happened because the deletion icon would use the selected entry
index to choose what branch to delete. This works for all cases except
when hovering on an entry, so the fix was passing in the entry index to
the deletion button on_click handler.

I also disabled the deletion button from working if a branch is HEAD,
because it's an illegal operation to delete a branch a user is currently
on.

Finally, I made WeakEntity<Workspace> a non-optional field on
`BranchList` because a workspace should always be present, and it's used
to show toast notifications when a git operation fails. The popover view
wouldn't have a workspace before, so users wouldn't get error messages
when a git operation failed in that view.

Fixes the hang introduced in #44995 (which was reverted in #45011) and
re-enables the optimization.

## Background

PR #44995 introduced an optimization to skip rendering lines that are
clipped by parent containers (e.g., when a large AutoHeight editor is
inside a scrollable List). This significantly improved performance for
large diffs in the Agent Panel.
However, #45011 reverted this change because it caused the main thread
to hang for 100+ seconds in certain scenarios, requiring a force quit to
recover.

## Root Cause
The original analysis in #45011 suggested that visible_bounds wasn’t
being intersected properly, but that was incorrect—the intersection via
with_content_mask works correctly. The actual bug: when an editor is
positioned above the visible viewport (e.g., scrolled past in a List),
the clipping calculation produces a start_row that exceeds max_row:

1. Editor’s bounds.origin.y becomes very negative (e.g., -10000px)
2. After intersection, visible_bounds.origin.y is at the viewport top
(e.g., 0)
3. clipped_top_in_lines = (0 - (-10000)) / line_height = huge number
4. start_row = huge number, but end_row is clamped to max_row
5. This creates an invalid range where start_row > end_row

This caused two different failures depending on build mode:
- Debug mode: Panic from subtraction overflow in
Range<DisplayRow>::len()
- Release mode: Integer wraparound causing blocks_in_range to enter an
infinite loop (the 100+ second hang)

## Fix

Simply clamp start_row to max_row, ensuring the row range is always
valid:

```rs
let start_row = cmp::min(
    DisplayRow((scroll_position.y + clipped_top_in_lines).floor() as u32),
    max_row,
);
```

## Testing
Added a regression test that draws an editor at y=-10000 to simulate an
editor that’s been scrolled past in a List. This would panic in debug
mode (and hang in release mode) before the fix.

Release Notes:
- Improved agent panel performance when rendering large diffs.
