## Summary

Add `workspace::ActivateLastPane` so users can bind a shortcut (for
example `cmd-9`) to focus the last pane.

## Why

Today, the closest option is `workspace::ActivatePane` with an index
(for example `8`), but that has side effects: when the index does not
exist, it creates/splits panes (`activate_pane_at_index` fallback).

`ActivateLastPane` gives a stable, no-surprises target: focus the
rightmost/last pane in current pane order, never create a new pane.

## Context

This capability has been requested by users before:
- https://github.com/zed-industries/zed/issues/17503#event-22959656321

## Prior art

VS Code exposes explicit editor-group focus commands and index-based
focus patterns (e.g. `workbench.action.focusSecondEditorGroup` ...
`focusEighthEditorGroup`) in its workbench commands:
-
https://github.com/microsoft/vscode/blob/main/src/vs/workbench/browser/parts/editor/editorCommands.ts#L675-L724

Zed already follows numbered pane focus in default keymaps
(`ActivatePane` 1..9 on macOS/Linux/Windows), so adding a dedicated
"last pane" action is a small, natural extension:
- `assets/keymaps/default-macos.json`
- `assets/keymaps/default-linux.json`
- `assets/keymaps/default-windows.json`

## Change

- Added `workspace::ActivateLastPane`
- Implemented `Workspace::activate_last_pane(...)`
- Wired action handler in workspace listeners
- Added `test_activate_last_pane`

## Validation

- `cargo test -p workspace test_activate_last_pane -- --nocapture`
- `cargo test -p workspace test_pane_navigation -- --nocapture`
- `cargo fmt --all -- --check`

## Risk

Low: focus-only behavior, no layout/data changes, no default keymap
changes.

Release Notes:

- Added `workspace::ActivateLastPane` action for keybindings that focus
the last pane.

The AI-assisted "Review Diff" action was only working for committed
changes because we were passing HEAD in the git command. Without it, it
captures all of the working tree changes, the same way the Branch Diff
view itself does. I think this is now better and more intuitive, because
it shouldn't be required that you commit the changes to have them
quickly reviewed by an agent.

Closes #40602

### Summary

This PR ensures that active debug lines only open in a single pane and
new active debug lines are added to the most recent pane that contained
an active debug line. This fixes a bug where Zed could go to the active
debug line file and location in every pane a user had open, even if that
pane was focused on a different file.

I fixed this by storing the `entity_id` of the pane containing the most
recently active debug line on `BreakpointStore`, this is consistent with
where the selected stack frame is stored. I used an `entity_id` instead
of a strong type to avoid circular dependencies. Whenever an active
debug line is being set in the editor or by the debugger it now checks
if there's a specific pane it should be set in, and after setting the
line it updates `BreakpointStore` state.

I also added a new method on the `workspace::Item` trait called `fn
pane_changed(&mut self, new_pane_id: EntityId, cx: &mut Context<Self>)`
To enable `Editor` to update `BreakpointStore`'s active debug line pane
id whenever an `Editor` is moved to a new pane.

Follow-up to #45600.

## Summary

Fix mouse scroll reports sending only one event when scrolling down in
terminal apps with mouse mode (tmux, neovim, etc.), regardless of how
many lines were scrolled.

## The Problem

After #45600, trackpad scrolling speed was fixed. But when scrolling
**down** (negative `scroll_lines`), the terminal was still sending only
**one** scroll report per gesture, no matter how many lines the user
scrolled. Scrolling up worked correctly.

## Root Cause

In `scroll_report()` we had:

https://github.com/zed-industries/zed/blob/a8043dcff8f28a0443d7ec238e7f020689ebe1ff/crates/terminal/src/mappings/mouse.rs#L96

`scroll_lines` can be negative (scroll down) or positive (scroll up).
For negative values:

| scroll_lines | max(scroll_lines, 1) | Reports sent | Verdict |
|--------------|---------------------|--------------|------|
| 3 (up)       | 3                   | 3           |Right
| -3 (down)    | 1                   | 1           |WRONG|

So we always sent exactly 1 report when scrolling down, losing the
scroll magnitude.

Use `scroll_lines.unsigned_abs()` instead of `max(scroll_lines, 1)`.
This matches how `alt_scroll()` in the same file already handles
`scroll_lines`. Now both directions send the correct number of reports.

https://github.com/zed-industries/zed/blob/a8043dcff8f28a0443d7ec238e7f020689ebe1ff/crates/terminal/src/mappings/mouse.rs#L102

## Testing

- Added unit tests: `scroll_report_repeats_for_negative_scroll_lines`
and `scroll_report_repeats_for_positive_scroll_lines`
- Manually tested scrolling in tmux and neovim with mouse mode

one scroll event when scrolling down, regardless of scroll amount

We see a number of crashes in Sentry that appear to be crashes in
wasmtime.
This shouldn't happen, as wasmtime is designed to run untrusted code
"safely".

Looking into this, it seems likely that the problem is that we race with
wasmtime
when installing signal handlers. If wasmtime's handlers are installed
before ours,
then any signals that it intends to handle (like out of bounds memory
access) will
reach our handlers before its; which causes us to assume the app has
crashed.

This changes fixes our crash handler initialization to ensure we always
create
our signal handler first, and reverts a previous attempt to fix this
from #40883

This PR adds a more rigorous test for the excerpt syncing logic in
`SplittableEditor`, in preparation for refactoring that code, since
we've had some bugs there.

The new test covers
- edits within the RHS multibuffer
- edits to the individual main buffers, not necessarily within the
excerpt bounds of the split diff
- excerpt expansion
- excerpt removal
- excerpt recalculation based on diff hunk ranges

Bugs fixed:
- incorrect edit merging logic in `patches_for_range`
- `merge_excerpts` leaving stale excerpt IDs in `excerpts_by_path`

## Summary

Fork PRs don't have access to repository secrets (`FACTORY_API_KEY`),
causing the docs suggestions workflow to fail when triggered by external
contributor PRs.

This adds a condition to skip the `batch-suggestions` job when the PR
originates from a fork (`github.event.pull_request.head.repo.full_name
!= github.repository`).

## Context

See failing job:
https://github.com/zed-industries/zed/actions/runs/22323201362/job/64586740764

The `pull_request` trigger doesn't pass secrets to workflows running on
fork PRs for security reasons. This is expected GitHub behavior.

An alternative approach would be to use `min_w` instead of `w`, but that
would result in inconsistent widths across the three tabs in the git
picker, causing layout jumps when switching between them. It might be
more appropriate to simply increase the width directly.

## Summary
Align right-side controls in settings rows when descriptions wrap to
multiple lines, and relax the text-width cap for better balance.

## Changes
- Top-aligned settings row containers in shared settings UI render paths
by adding `items_start()` to:
  - Setting rows (`render_settings_item`)
  - Sub-page link rows
  - Action link rows
- Updated the left text column width constraint in
`render_settings_item` from `w_3_4` to `w_full + max_w_2_3 + min_w_0` to
avoid overlap while reducing excess empty space.

## Validation
- Built and ran Zed locally with `cargo run`.
- Manual verification in Settings pages with multiline descriptions and
right-side controls:
  - General
  - Appearance
  - Languages & Tools
  - Agent/Terminal-related sections
- Confirmed improved control alignment and no right-column text overlap
in the tested views.

Previously, we were not computing excerpt regions correctly for EP
examples captured from prod. This PR fixes that, and also simplifies the
data flow in the EP CLI. Examples either come from a concise spec (like
the markdown evals), or are collected from prod. Either way, we compute
from them a `ZetaPromptInput`, and the downstream steps like
prompt-formatting and scoring are derived from that.

In addition to the thinking tokens causing overhead, we were slowing
down file editing even more. because changing between
thinking/non-thinking between requests causes the cache to be
invalidated
([docs](https://platform.claude.com/docs/en/build-with-claude/prompt-caching#what-invalidates-the-cache)).

For the last few days, the model has never picked a good timeout value.
It seems they are better at choosing timeouts for bash commands but not
agents. Given there are some rate limits involved, I think it is hard to
estimate and we already have an upper bound of execution which is the
context window to keep it from going indefinitely.
