Closes #47098 

The root cause of this issue is related to how `Poetry` (and the
upstream `pet-poetry` library) handles path hashing. While perhaps it's
an upstream behavior, we can easily fix it on the Zed side.

The related code are

https://github.com/zed-industries/zed/blob/7ce845210d3af82a57a7518e0abe8c167d60cc6a/crates/languages/src/python.rs#L1181-L1211

In my debugging, I found that `worktree_root` takes the form
`/home/user/project`, but `config.workspace_directories` often ends up
as `/home/user/project/`(with a trailing slash). Normally this wouldn't
be an issue, but `Poetry` generates environment names based on the hash
of the absolute path. Since the hashes for `/home/user/project` and
`/home/user/project/` are different, `pet-poetry` fails to find the
environment.

The fix is straightforward: we just need to ensure the trailing `/` is
removed so the hashes match.

Release Notes:

- Fixed poetry environment not discovered on linux

Fixes an unintended behavioral change from #40838.

The settings store separate themes for Light and Dark modes. When the
user clicks a theme, the code uses the system appearance to decide which
to update, rather than the mode the user selected in the UI. This causes
the wrong theme to be saved when the system appearance differs from the
selected mode.

Closes https://github.com/zed-industries/zed/issues/46519

This crash happened because we were incorrectly merging pending and
unstaged hunks together by always using the pending hunk end offset as
the merged hunk bound instead of the max of both hunks.

The fix is to use `max()` when updating `buffer_offset_range.end` during
pending hunk merging, matching the behavior used for unstaged hunk
merging.

Closes #46328

Release Notes:

- Fixed agent model selector cutting off models at the end of the list.

## Problem

When subagents use the `edit_file` tool, it creates an `EditAgent` that
makes its own model request to get the edit instructions. These "nested"
requests compete with the parent subagent conversation requests for rate
limiter permits.

The rate limiter uses a semaphore with a limit of 4 concurrent requests
per model instance. When multiple subagents run in parallel:

1. 3 subagents each hold 1 permit for their ongoing conversation streams
(3 permits used)
2. When all 3 try to use `edit_file` simultaneously, their edit agents
need permits too
3. Only 1 edit agent can get the 4th permit; the other 2 block waiting
4. The blocked edit agents can't complete, so their parent subagent
conversations can't complete
5. The parent conversations hold their permits, so the blocked edit
agents stay blocked
6. **Deadlock**

## Solution

Added a `bypass_rate_limit` field to `LanguageModelRequest`. When set to
`true`, the request skips the rate limiter semaphore entirely. The
`EditAgent` sets this flag because its requests are already "part of" a
rate-limited parent request.

(No release notes because subagents are still feature-flagged.)

Overview

Restructures the documentation navigation to be organized by user goals
rather than feature lists. Introduces a new "Working with Code" section
and reorganizes existing content into clearer groupings.

### Navigation Changes

**New top-level sections:**
- **Working with Code** — Groups editing, navigation, and execution
features by workflow
- **Reference** — Dedicated section for lookup-only content (settings,
actions, CLI)
- **Coming From...** — Migration guides grouped together

**Reorganized sections:**
- **Customization** — Renamed from "Configuration," focused on
appearance and keybindings
- **Account & Privacy** — Consolidated auth, privacy, and telemetry
pages

Follow-Up-For:  #47243

Previously, we would detach tasks spawned to watch config files.
However, the task blocked on receiving a file event before checking if
the receiver for the updates channel was dropped, causing the task to
never exit. The fix here was to return the task explicitly, so that it
can be dropped instead of calling `.detach()` on it. There is definitely
a way to `select!` between the receiver being dropped and the next file
system event, but I couldn't figure it out in a reasonable amount of
time and decided it wasn't worth it.

This PR adds the ability to edit a queued message, which you can now do
by hitting `cmd-e` from the message editor, which will focus the first
queued message. To pull that off, I'm also making the queued messages
render as an editor, the same way we do with regular user messages. That
way, we ensure less layout shift when focusing in and out of the queued
message for editing and gain the ability to render context
buttons/creases the same way we do in the main message editor.

Note that in the video, I show the state in which you're still editing
in the moment in which the queued message would be sent. If that
happens, your queued message won't be sent even if you unfocus the
queued message editor. In this case, you need to explicitly hit "Send
Now".

## Summary

Fixes crash when dragging debugger panel items
(terminal/console/variables/frames) to another pane as split view.

  **Root causes:**
1. Double borrow panic - `pane_group.split()` was called synchronously
inside a `Context<Pane>` update, causing "cannot update Pane while it is
already being updated"
2. `unwrap()` calls that panic when items are in transition during drag
operations
3. `debug_assert!` in `pane_at_pixel_position` fails when `members` and
`bounding_boxes` are temporarily out of sync after deferred split

  **Fixes:**
- Defer entire split+move operation via `cx.spawn_in()` to avoid double
borrow
- Replace `unwrap()` with graceful early returns in `activate_item` and
`run_in_terminal`
- Handle `members.len() != bounding_boxes.len()` gracefully in
`pane_at_pixel_position`

This command takes raw LLM outputs (`predictions.actual_output`) that
could be generated elsewhere and parses them into a canonical unified
diff (`predictions.actual_patch`).

This is useful for simplifying the evaluation pipeline and for rerunning
the parser without having to generate LLM outputs.

# Diagnostics Mention in New Threads

## Overview

Adds the `@diagnostics` mention to the new Agent Panel threads so users
can inject current LSP diagnostics (errors by default) without switching
to a text thread. The diagnostics mention is fully integrated into ACP
mention parsing, the context picker, and the message-editor pipeline so
it round-trips cleanly and shows up in the standard `@` menu.

## Context

- **Request:** bring `/diagnostics` parity to the “New Thread” assistant
experience.
- **Scope:** diagnostics only; `/terminal` mention would be implemented
in a separate PR.
- **Docs:** updated Agent Panel docs + changelog.

## Implementation Details

1. **Mention plumbing**
- Added `MentionUri::Diagnostics` to `acp_thread`, including parsing
(`zed:///agent/diagnostics?include_warnings=true`) and icon/name
metadata.
- Tests ensure diagnostics links round-trip via Markdown mention
serialization.

2. **Context picker / completion**
- New `ContextPickerMode::Diagnostics` exposes an `@diagnostics` entry
in the mention menu.
- Completions turn `@diagnostics` into a fully fledged mention, reusing
the existing confirmation pipeline.

3. **Message editor + thread serialization**
- Resolving the mention calls the existing diagnostics collector from
`assistant_slash_commands`, embedding the tool output inline with other
context blocks (`<diagnostics>…</diagnostics>`).
- Thread-link handling ignores diagnostics backlinks so clicking them
doesn’t try to reopen nonexistent resources.

The issue here was that we were not looking into the sub page stack when
looking headers up, resulting in an out of bounds index. This PR fixes
this.

Due to me also fixing another small bug in the UI (and adding proper
support for the breadcrumbs), I had to move quite some stuff around here
to get this to work. Namely, I made the `sub_page_stack` a field on the
`SettingsWindow` and now only store the `active_language` in a global to
ensure that we store scroll positions properly for all sub pages. For
that to work with the edit prediction provider page, I had to remove the
struct there and could just move that into a method, which was a nice
side effect there I suppose.

- Fixed a crash that could occur when trying to edit edit prediction
providers in the settings UI.
