build_root_plan now returns None for non-linked (main) worktrees,
so archiving a thread that lives on a main worktree no longer
attempts `git worktree remove` (which git rightfully refuses).

The thread is simply marked archived in the metadata store and can
be unarchived later without any git operations.

Since build_root_plan now guarantees a linked worktree,
RootPlan::worktree_repo is changed from Option<Entity<Repository>>
to Entity<Repository>, removing the fallback path and the
now-unnecessary is_some() guard in archive_worktree_roots.

Closes #52928

Release Notes:

- Fixed handling of multi-stage and stage-specified dockerfiles in dev
container manifests
- Fixed the way we find the base image in a dev container when build
args need expansion

The "Creating Worktree…" spinner, error banner, and disabled selector
state were stored as panel-wide state. This meant switching to a
different thread while a worktree was being created would still show the
spinner on the new thread.

Release Notes:

- N/A

Disambiguate project names in the sidebar (and project picker) so that
we don't show e.g. `zed, zed` but rather `foo/zed, bar/zed` if the last
path component is the same but they are different absolute paths.

Release Notes:

- The "Fix with Assistant" code action for diagnostics has been removed.
The inline assistant remains available and can be deployed with the
`assistant: inline assist` action.

Update `await_and_rollback_on_failure` in `agent_panel.rs` to
comprehensively clean up both git metadata and filesystem artifacts when
worktree creation fails.

Release Notes:

- Clean up files and git metadata when worktree creation fails during
new agent thread setup.

- Introduce `project_panel::Redo` action
- Update all platform keymaps in order to map
`redo`/`ctrl-shift-z`/`cmd-shift-z` to the `project_panel::Redo` action

### Restore Entry Support

- Update both `Project::delete_entry` and `Worktree::delete_entry` to
return the resulting `fs::TrashedEntry`
- Introduce both `Project::restore_entry` and `Worktree::restore_entry`
to allow restoring an entry in a worktree, given the `fs::TrashedEntry`
- Worth pointing out that support for restoring is not yet implemented
for remote worktrees, as that will be dealt with in a separate pull
request
  
### Undo Manager

- Split `ProjectPanelOperation` into two different enums, `Change` and
`Operation`
- While thinking through this, we noticed that simply recording the
operation that user was performing was not enough, specifically in the
case where undoing would restore the file, as in that specific case, we
needed the `trash::TrashedEntry` in order to be able to restore, so we
actually needed the result of executing the operation.
- Having that in mind, we decided to separate the operation (intent)
from the change (result), and record the change instead. With the change
being recorded, we can easily building the operation that needs to be
executed in order to invert that change.
- For example, if an user creates a new file, we record the
`ProjectPath` where the file was created, so that undoing can be a
matter of trashing that file. When undoing, we keep track of the
`trash::TrashedEntry` resulting from trashing the originally created
file, such that, redoing is a matter of restoring the
`trash::TrashedEntry`.
- Refer to the documentation in the `project_panel::undo` module for a
better breakdown on how this is implemented/handled.

- Introduce a task queue for dealing with recording changes, as well as
undo and redo requests in a sequential manner
- This meant moving some of the details in `UndoManager` to a
`project_panel::undo::Inner` implementation, and `UndoManager` now
serves as a simple wrapper/client around the inner implementation,
simply communicating with it to record changes and handle undo/redo
requests
- Callers that depend on the `UndoManager` now simply record which
changes they wish to track, which are then sent to the undo manager's
inner implementation
- Same for the undo and redo requests, those are simply sent to the undo
manager's inner implementation, which then deals with picking the
correct change from the history and executing its inverse operation
- Introduce support for tracking restore changes and operations
- `project_panel::undo::Change::Restored` – Keeps track that the
file/directory associated with the `ProjectPath` was a result of
restoring a trashed entry, for which we now that reverting is simply a
matter of trashing the path again
- `project_panel::undo::Operation::Restore` – Keeps track of both the
worktree id and the `TrashedEntry`, from which we can build the original
`ProjectPath` where the trashed entry needs to be restored
- Move project panel's undo tests to a separate module
`project_panel::tests::undo` to avoid growing the
`project::project_panel_tests` module into a monolithic test module
- Some of the functions in `project::project_panel_tests` were made
`pub(crate)` in order for us to be able to call those from
`project_panel::tests::undo`
  
### FS Changes

- Refactored the `Fs::trash_file` and `Fs::trash_dir` methods into a
single `Fs::trash` method
- This can now be done because `RealFs::trash_dir` and
`RealFs::trash_file` were simply calling `trash::delete_with_info`, so
we can simplify the trait
- Tests have also been simplified to reflect this new change, so we no
longer need a separate test for trashing a file and trashing a directory
- Update `Fs::trash` and `Fs::restore` to be async
- On the `RealFs` implementation we're now spawning a thread to perform
the trash/restore operation

Introduce a new `fs::Fs::restore` method which, given a
`fs::TrashedEntry` should attempt to restore the file or directory back
to its original path.

Update both `Fs::trash_dir` and `Fs::trash_file` to now return the
location of the trashed directory or file, as well as adding the
`trash-rs` create dependency and updating the `RealFs` implementation
for these methods to simply leverage `trash::delete_with_info`.

* Add `fs::Fs::TrashedEntry` struct, which allows us to track the
  original file path and the new path in the OS' trash
* Update the `fs::Fs::trash_dir` and `fs::Fs::trash_file` signatures to
  now return `Result<TrashedEntry>` instead of `Result<()>`
* The `options` argument was removed because it was never used by
  implementations other than the default one, and with this change to
  the signature type, we no longer have a default implementation, so the
  `options` argument would no longer make sense
* Update `fs::RealFs::trash_dir` and `fs::RealFs::trash_file`
  implementations to simply delegate to `trash-rs` and convert the
  result to a `TrashedEntry`
* Add `fs::FakeFs::trash` so we can simulate the OS' trash during tests
  that touch the filesystem
* Add `fs::FakeFs::trash_file` implementation to leverage
  `fs::FakeFs::trash`
* Add `fs::FakeFs::trash_dir` implementation to leverage
  `fs::FakeFs::trash`

This panic was caused because we incorrectly assumed that each character
was one byte when converting character indices to highlight range byte
indices.

When git commands (push, pull, hooks...) produce output containing ANSI
escape sequences for colors or formatting, Zed was displaying them as
raw escape codes in the output buffer, making the output hard to read.
This simply escapes ANSI from the git output

Related to #43817. This PR only addresses the escaping of the ANSI
codes; colors and other stuff are not handled

Release Notes:

- Fixed ANSI escape codes being displayed as raw text in git command
output

This PR greatly improves our handling of remote threads in the sidebar.

One primary issue was that many parts of the sidebar were only looking
at a thread's path list and not its remote connection information. The
fix here is to use `ProjectGroupKey` more consistently throughout the
sidebar which also includes remote connection information.

The second major change is to extend the MultiWorkspace with the ability
to initiate the creation of remote workspaces when needed. This involved
refactoring a lot of our remote workspace creation paths to share a
single code path for better consistency.

Release Notes:

- (Preview only) Fixed remote project threads appearing as a separate
local project in the sidebar

Closes #47140
Closes #44691

When launching Zed from the CLI (`zed .`), macOS delivers the path as a
`kAEGetURL` Apple Event via Launch Services. Zed relied on the
`application:openURLs:` delegate method to receive this, but its timing
relative to `applicationDidFinishLaunching:` is not guaranteed by macOS.
In release builds, the app reaches `didFinishLaunching` before the URL
is delivered, causing it to be missed and a duplicate window to be
opened. This does not reproduce in debug builds due to slower
initialization, which is why the issue was hard to reproduce from
source.

This replaces `application:openURLs:` with a custom `kAEGetURL` Apple
Event handler registered in `applicationWillFinishLaunching:`. Apple
Events are guaranteed to be delivered synchronously between
`willFinishLaunching` and `didFinishLaunching`, ensuring the URL is
always available before startup logic runs.

 Release Notes:

- Fixed duplicate window creation when opening files/directories from
the CLI on macOS.

This PR removes the labeled "new thread" button when the project group
is empty, making it so, effectively, we only show it when you're in an
empty/draft thread in the active workspace. The "Untitled Thread" label
has also been renamed back to "New Thread". Then, we fixed an issue
where clicking on the new thread icon button would default to creating a
new thread in the main worktree as opposed to the one currently active;
this fix makes the button's behavior match with `cmd-n` from the agent
panel. Lastly, we fixed the "new thread" labeled button not opening the
agent panel when that's closed and organized the data structures a bit
by merging `DraftThread` and `NewThread` all into `DraftThread`.

Release Notes:

- Thread Sidebar: Fixed the new thread icon button not creating a thread
in the current active worktree.
- Thread Sidebar: Fixed click on the new thread button not opening the
agent panel when closed.

Connect the git API and archived worktree data model to the sidebar's
archive/unarchive flow:

- Add `thread_worktree_archive` module: orchestrates the full archive
cycle (WIP commits, DB records, git refs, worktree deletion) and restore
cycle (detached worktree creation, reset to recover staged/unstaged
state, branch restoration)
- Integrate into sidebar: `archive_thread` now persists worktree state
before cleanup; `activate_archived_thread` restores worktrees via git
with targeted path replacement for multi-root threads
- Add pending worktree restore UI state with spinner and cancel button
- Show toast on restore failure instead of silent log
- Switch to surviving workspace when archiving active thread whose
workspace will be deleted
- Deserialize persisted `project_group_keys` on window restore
- Guard `cleanup_empty_workspaces` against dropped entities
- Await rollback DB operations instead of fire-and-forget

Part 3 of 3 in the persist-worktree stack. Stacked on #53214. This wires
up parts 1 and 2.

Release Notes:

- Added worktree state preservation when archiving agent threads,
automatically restoring staged and unstaged changes when the thread is
unarchived

In `update_git_repositories`, a `.git` path outside the worktree root
can occur legitimately when `.git` is a gitfile (as in linked worktrees
and submodules) pointing to a directory in the parent repo. Previously
this triggered a `debug_panic!`, crashing debug builds.

Now we skip the path with a `debug_assert!` that it is indeed a file
(not a directory), so a genuine `.git` directory outside the worktree
root would still be caught in debug builds.

https://github.com/zed-industries/zed/pull/53215 lands)

When toggling fast mode, the setting is now written to `settings.json`
under `agent.default_model.speed`, so new threads start with the same
speed. This follows the same pattern as `enable_thinking` and `effort`.

The `speed` field uses the existing `Speed` enum (`"fast"` /
`"standard"`) rather than a boolean, to leave room for future speed
tiers.

Example settings:
```json
{
  "agent": {
    "default_model": {
      "provider": "zed.dev",
      "model": "claude-sonnet-4",
      "speed": "fast"

### Summary
Fixes duplicated Prompts/context in ACP threads after sending a message,
as reported in #53201.

### Root Cause
The thread already inserts the user prompt optimistically at send time.
If an ACP server also echoes UserMessageChunk updates for the same
prompt, the same content is appended again, which can duplicate rendered
context sections.

### Fix
Ignore echoed UserMessageChunk updates while a turn is actively running,
so user prompt content is not appended twice.

### Validation
- Reproduced with OpenCode ACP flow from the issue.
- Confirmed duplication appears after send (not in the input box).
- Confirmed duplicate Prompts/context no longer appears with the fix.
