on top of `main`, `User` and `Agent` will always interleave.

This happens because `action_log` does updates on `Entity<Buffer>` which
is a current editor's buffer, tracked, and updated by agent output (acp
or regular threads) — those updates come back as `BufferEvent::Edited`
event after each agent's edit and forces unnecessary computations.

Instead, update tracked buffer's version after each agent update report
to only react on one, `Agent`-authored, edit events.

When a recorded action moves focus away from the editor (e.g.,
`buffer_search::Deploy`), the `EndRepeat` action handler is not invoked
because is node is no longer on the dispatch path. This left
`dot_replaying` set to `true`, causing subsequent repeats to malfunction
and the `VimGlobals.pre_count` value to never be reset.

Reset `dot_replaying` as a fail-safe when the replayer exhausts its
action queue, ensuring the state is always cleaned up regardless of
whether `EndRepeat` was handled.

Release Notes:

- Fixed vim repeat (`.`) breaking when the recorded action moves focus
away from the editor

The `vim` crate's tests depend on `git_ui`, which transitively depends
on `recent_projects` with `test-support` enabled. This causes
`recent_projects` to include RemoteConnectionOptions::Mock` variant
handling. However, `git_ui` was not enabling its `test-support` feature,
causing compilation failures when the Mock variant was expected but not
available.

This commit enables the `test-support` feature for both `git_ui` and
`title_bar` dev-dependencies in the `vim` crate, ensuring the Mock
variant is consistently available during testing.

When the user presses Esc or the Stop button to interrupt a thread,
terminal tools now capture their output and include it in the tool
result. This allows the model to see what was happening in the terminal
when the user interrupted, so it can answer questions about the output.

## Changes

- `Thread::cancel()` now returns a `Task` that waits for tools to
respond to cancellation before flushing pending messages
- Terminal tool uses `select!` to detect cancellation signal and
immediately kills the terminal and captures output
- `run_turn_internal` uses `select!` to break out of event loop on
cancel
- Added test for terminal tool cancellation output capture

This is a follow-up to #46218 which added similar functionality for the
"Stop" button on individual terminal tool cards.

Release Notes:

- Interrupting the agent now captures terminal output so the model can
see what was running when you stopped it

Release Notes:

- The inline assistant now has the ability to display messages and will
be less likely to insert non-code text.

Adds a new `ep split` command that splits JSONL datasets into multiple
output files with stratification by `repository_url` when present.

## Description
When trying to setup the OpenCode external agent the other day, I was
having trouble setting the keybinding using the docs. The issue was that
it said to use the same name as the one written in the UI. While this
works when the external agent is defined using the `settings.json` file,
it didn't work when setting up the keybinding after installing the
extension through the extension marketplace.

Since the solution I found was to define the agent name as 'opencode'
instead of 'OpenCode' (which is the name that shows up in the UI) I
thought it would be appropiate to indicate that sometimes you might need
to set it up using a different name.

Closes #44038

BM25 results were fully replacing fuzzy results, which caused some items
to disappear from search. For example, "Show Menus" wouldn’t show up
when searching for "menu". This happened due to limitations in the
Porter stemmer used by the library. Fuzzy search matched correctly, but
its results were getting overwritten. We now merge both result sets
instead.

Release Notes:

- Fixed an issue where settings search missed some results, like "Show
Menus" when searching for "menu".

Un-preview the active tab when closing other tabs. 

In my mind the intent when clicking `Close Others` is to keep the
current tab around, so it should no longer be treated as a preview.
This also matches the VSCode behavior.


Release Notes:

- Make preview tab permanent after closing all other tabs

Fixes #33958

## Problem

PR #44835 attempted to fix SHLVL starting at 2 by removing it from the
`env` HashMap passed to alacritty. However, that HashMap is only an
**overlay** — alacritty uses the parent process environment as a base
and applies the overlay on top. Since alacritty never calls
`env_remove("SHLVL")`, the terminal shell still inherits `SHLVL` from
Zed's process environment.

## Root Cause

The real issue is in `load_login_shell_environment()`:

1. `shell_env::capture()` spawns a login shell to capture environment
variables
2. That login shell increments `SHLVL` (from 0→1 or n→n+1)
3. The captured env (including the incremented `SHLVL`) is written to
Zed's **process environment** via `env::set_var`
4. When you open a terminal, the shell inherits Zed's `SHLVL` and
increments it again → starts at 2
5. On reload, `shell_env::capture()` runs again with the
already-elevated `SHLVL`, incrementing it further → +2 per reload

## Fix

Skip `SHLVL` when setting Zed's process environment in
`load_login_shell_environment()`. This prevents the login-shell capture
from polluting Zed's env, so terminals start fresh with the correct
`SHLVL`.

Release Notes:

- Improved Display the actual Windows error message when writing
credentials to Credential Manager fails, instead of the generic "Failed
to write API key to keychain" message. This helps users diagnose issues
like permission problems.

Hi Zed team thank you for the awesome editor!

I recently stumbled upon a markdown sequence that seems to cause a crash

```md
-	[	] -
\
-
```

*easier to read escape characters below

```rust
let crash_input = "-\t[\t] -\r\\\n-"
println!("{}", crash_input)
```

## how to reproduce

1. copy the markdown above
2. save the file
3. `[shift]` + `[cmd]` + `p` to open the command palette
4. select `markdown: open preview`
5. crash

I've confirmed that the issue is a bug in pulldown-cmark version 12, and
has been resolved in version
[v0.13.0](https://github.com/pulldown-cmark/pulldown-cmark/releases/tag/v0.13.0)
and specifically fixed in
https://github.com/pulldown-cmark/pulldown-cmark/pull/1017

this PR simply bumps the pulldown-cmark version in zed which resolves
the crash on my local machine.

## Add variable row height mode to data table infrastructure

This PR introduces support for variable row heights in the data table
component, laying the groundwork for more flexible tabular data
rendering in Zed.

**Context:**  
This is the first in a series of infrastructure-focused PRs split out
from the [original CSV preview draft
PR](https://github.com/zed-industries/zed/pull/44344). The draft PR
remains open as a reference and will be incrementally decomposed into
smaller, reviewable pieces like this one.

**Details:**  
- Adds a variable row height mode to the data table, enabling future
features that require rows of differing heights (such as CSV preview
and, eventually, database table views).
- No user-facing changes; this is an internal refactor to support
upcoming functionality.

**Thanks:**  
Big thanks to @Anthony-Eid for pairing sessions and guidance on how to
best structure and land these changes incrementally.

Closes #ISSUE

Organizes the giant list of settings UI items in `page_data.rs` a bit so
that sections are split out in sub functions that (for the most part)
return constant size arrays. Page items is also converted to a
`Box<[...]>` instead of a Vec.

The goal here is to have working breadcrumbs when in the settings UI
file (e.g. `fn general_page() > fn general_section()`), and to escape
the `vec![]` macro so that `rust-analyzer` works more consistently.

This should help both humans and LLMs know where they are in the file
and use the outline to navigate it instead of having to read the whole
thing to have an idea of what is going on.

The tree view effectively always sorts by status, not by path.

Release Notes:

- Fixed incorrect ordering of paths in the project diff when using the
git panel's tree view.

https://github.com/zed-industries/zed/pull/45423 changed the Blade
renderer to use a white clear color for "opaque" windows. This interacts
poorly with our client-side decorations, causing the shadows around the
window to be drawn over a white background.

This is only applicable to vim search.

- Replace `is_new_file: bool` with `FileStatus` enum
(Created/Modified/Deleted) in udiff.rs to properly track file status
through diff operations
- Handle deleted files in `apply_diff` by calling
`project.delete_file()`
- Fix diff serialization in reorder_patch.rs to output `+++ /dev/null`
for file deletions and parse both `--- /dev/null` and `+++ /dev/null`
correctly
- Add bounds check for edit ranges exceeding buffer length

Also includes edit_prediction_cli improvements:
- Track `context_range` and `editable_range` in ExampleBuffer for more
precise prompt formatting
- Export MAX_CONTEXT_TOKENS and MAX_REWRITE_TOKENS from zeta2
- Wait for buffer parsing before computing ranges
- Respect NO_COLOR env var and enable info-level logging

Remove the attempts to have these issues land in the same 'inbox' (the
existing project board for triage). Since they're closed, the automated
workflow of the project board will move them to the 'Closed'
column/status even with the API call specifically moving them to
'Incoming' instead. It is what it is, we'll have a separate project
board for this.

Also:
- don't look at comments on PRs
- don't freak out if the issue has no type
- add a permissions block as a defensive measure (in case someone adds
secrets.GITHUB_TOKEN later)
- add a timeout to avoid hanging out for six hours or whatever the
default is
- add some logging.

`extract_last_codeblock` was using `find()` to locate closing fences,
which would match backticks anywhere in the text. This caused incorrect
parsing when the content contained inline backticks or nested code
blocks, resulting in wrong diffs.

Fix by requiring the closing fence to be preceded by a newline.

Previously, if you stopped the terminal prematurely, the agent would
assume the terminal process had timed out. Now it knows what happened
and can see the output:

Release Notes:
- Stopping the terminal tool now allows the agent to see its output up
to that point.

Additionally this extracts more functionality into the RunnableVariant which is renamed to GpuiRunnable.
