Part of #48241 (`dsq` still needs to be implemented, I can try to do in
another PR if+when this is merged)

AnyBrackets was already supported, and these various surrounds were
supported with other vim motions, this just brings parity for "change
surrounds".
	
Also adds MiniBrackets support since it works the same way as MiniQuotes
does.

Most of this change is just test cases for vim edits with `csq` + `csb`,
using the keybinds described in the docs:
https://zed.dev/docs/vim#any-bracket-functionality

Also did a slight refactor to reuse some constants for supported pairs,
for consistency.


Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)

Release Notes:

- Fixed vim `change surrounds` for MiniQuotes, MiniBrackets, and
AnyQuotes

Release Notes:

- Added a `Copy Tag` action to the git graph context menu.

Right now the recent project picker has different confirm behavior
depending on if a user had open their sidebar in their current Zed
session. If the sidebar had been open the recent project picker adds the
selected project to the multi workspace and makes it the active
workspace, without removing anything. If the sidebar hadn't been open
the recent project picker would replace the active workspace within the
multi workspace.

This caused confusion because the same UX flow had two different
outcomes depending on Zed's state that wasn't obvious to users. This PR
mitigates this by always adding the project to the window while AI
features are enabled. Future follow ups will include the ability to
disable the sidebar, but that's blocked on the agent panel not having a
way to view active threads currently.

This also caused issues in the parallel agents workflow because
replacing a workspace would drop the workspace, thus causing any
terminal processes or threads to be dropped as well.

## Summary

Filenames containing markdown syntax (e.g. `__somefile__`, `*somefile*`)
were being rendered as formatted text in the git discard confirmation
dialog.

Follow-up to #55697 for the git discard confirmation path mentioned in
#53060.

## Changes

Wrapped the git discard confirmation filename with `MarkdownInlineCode`
in `git_panel.rs`, so special markdown characters like `_`, `*`, and `[`
render literally.

## Testing

Added `test_discard_prompt_escapes_markdown_in_file_name` in
`git_panel.rs` to verify filenames with markdown special characters
render literally in the discard confirmation dialog.

Run:
```bash
cargo test -p git_ui test_discard_prompt_escapes_markdown_in_file_name
```

Release Notes:

- Fixed file names containing markdown special characters (e.g.
`__somefile__`) being rendered as formatted text in the git discard
confirmation dialog.

Changes the sidebar filter editor placeholder from "Search…" to "Search
threads…" to make it clear what is being searched.

Release Notes:

- Improved sidebar search placeholder text to read "Search threads…"
instead of "Search…"

I wait for an agent it takes time/thinks, but I notice some odd error in
its work that I want to correct: I write a message, knowing that e.g.
Claude can read that later at some point and continue normally, and
focus away from Zed.

At some point, I get the notification I need to react to, only to
understand that the generation is ongoing still due to that delayed
message sent.

Release Notes:

- Fixed agent "finished" notification appearing right before the queued
message is sent

Closes #52042 

Release Notes:

- agent: Added setting `subagent_model` to specify which model is used
when subagent is spawned

This PR makes it so we route the `UserService::get_users_by_ids` call
through Cloud instead of hitting the database.

We've introduced a new `CloudUserService` that will fetch the users from
Cloud using the internal API. Note that we've only implemented the
`get_users_by_ids` method on this service, as the endpoints for the
other methods don't yet exist.

We have also introduced a `TransitionalUserService` for the purposes of
gradually transitioning these calls over to Cloud. Right now it uses the
`CloudUserService` for the `get_users_by_ids` implementation, but then
uses the `DatabaseUserService` for the other methods.

## Summary

Follow-up to https://github.com/zed-industries/zed/discussions/55352,
where the conclusion was to split `editor.rs` incrementally by topic
instead of all at once.

This mechanically extracts two editor topics into focused sibling
modules:

- `crates/editor/src/input.rs`
- `crates/editor/src/git.rs`

The git extraction is intentionally partial for now. I left a lot of
related parts because otherwise the diff was super huge (over 9K lines)
in the Github, so we can move those parts later in the follow-up PRs

* Adjusts the code lens display closer to what VSCode does: have blank
placeholders for the code lens need resolving.
Zed will remove them if resolve returns nothing, so some small amount of
jitter is still there.

* Also reworks LspStore layer to provide a simple resolve method,
without any ranges involved, grouping that logic in the editor itself.
This allows to process each resolve request separately, updating editor
blocks as soon as possible.

This PR fixes a few bugs, updates some UI, and improves testing of auto
watch. It'll likely be easier to review commit by commit:

- Swapped the Copy Channel Link and Auto Watch buttons so Auto Watch
appears in a better position. The UI is still not great, but I think
this tweak will improve it until someone on design can help.

/>


- Disable Auto Watch when following another collaborator, with test
coverage for that behavior. We currently disable following when engaging
auto watch, and now we disable auto watch when following. They are
mutually exclusive and I think the feels correct.
- Refactored Auto Watch integration tests to use channels API instead of
room API.
- Improved test robustness by using assertions to identify
`SharedScreen` items by type and `peer_id` instead of tab title text.
- Fixed Auto Watch for returning channel participants by emitting
`RemoteVideoTracksChanged` when removing a participant with active video
tracks, with regression coverage for leave/rejoin/share.

`render_settings_item_link` was calling `cx.read_from_clipboard()`
during render so it could show a check icon next to the copy-link button
when the matching link was on the clipboard. This had two problems:

- A clipboard read per visible setting per frame is too expensive.
- On Windows, reading the clipboard pumps the system message queue. If a
queued message handler updates `App` while we're still rendering, GPUI
panics with `RefCell already borrowed` (many occurrences observed).

Track the `json_path` of the most recently copied setting locally
instead. The check icon now reflects what was copied in this session via
this UI rather than whatever is on the system clipboard.

While this removes the most common offender, the underlying
`gpui_windows` reentrancy bug still exists: `on_close` /
`on_request_frame` callbacks can be invoked while `App` is already
borrowed on Windows, and can be triggered by any other
clipboard-touching code path. We should consider a follow-up PR that
handles this at the platform layer -- either by deferring callbacks that
re-borrow `App`, or by guarding individual handlers in
`gpui_windows::events` against reentrant `borrow_mut` calls.

Closes #48032 

When restoring a diff hunk, we first unstage it unconditionally. That
unstaging operation is a no-op in terms of the index text if the hunk
was already not staged, but previously we would still always do
`spawn_set_index_text_job` and bump the
`hunk_staging_operation_count_as_of_write`. Bumping that count in turn
causes us to skip a diff recalculation in response to the change in the
buffer's text. That works out fine in the local case, because when the
worktree picks up the write to `.git/index` we kick off another diff
recalculation which is not skipped. But in the remote case, we don't get
an `UpdateDiffBases` proto message if the index text didn't actually
change, so there is no subsequent diff calculation to do the cleanup,
and we end up with a stale no-op hunk.

This PR fixes the issue by skipping the write to the index and the
`hunk_staging_operation_count_as_of_write` bump if the new and old index
texts are the same.
