This PR adds persistence for threads in Assistant2.

Threads are now persisted to an LMDB database.

Release Notes:

- N/A

Fixes #23398 
Closes #23398

We'll bail on searches of files that we know are binary (thus even if we
were to find a match in them, they'd be thrown away by buffer loader).

Release Notes:

- Improved project search performance in worktrees with binary files

This PR cleans up some `use` statements that weren't at the very top of
the module.

Release Notes:

- N/A

This PR exposes the `thread` file on the `ActiveThread` via a getter
rather than exposing the field directly.

Release Notes:

- N/A

Makes the signatures more informative and can be more convenient as
multiple immutable borrows are allowed.

Release Notes:

- N/A

We don't want the zeta predictions entry to show in the assistant
context editor when completing slash commands. Zeta will still make
suggestions in the rest of the context editor, like the other providers
do.

Release Notes:

- N/A

Closes https://github.com/zed-industries/zed/issues/23512

Release Notes:

- Improved `editor: swap selection ends` by always scrolling the cursor
into view

This PR adds documentation for the `ZED_DEVELOPMENT_AUTH` environment
variable, in the hopes that it helps folks find it sooner.

Release Notes:

- N/A

This PR updates the `ListItem` component to not register an `on_click`
handler for `ListItem`s that are disabled.

When working on #23350 I noticed that even when the context menu entry
was disabled you could still click on the entry to fire the action.

Release Notes:

- Fixed some instances of disabled list items still registering clicks.

Closes #13979

Please review this approach to hide the permalink, or alternatively to
disable it instead?

Release Notes:

- The Copy Permalink menu item is now disabled when not in a Git
repository.

When clicking the checkbox label fire the toggle action.

At first I wasn't sure this is what we wanted, but after looking at a
few existing implementations of checkboxes with labels it seems like
this is reasonably standard.

Eventually this piece of UI will be updated to a CheckboxWithLabel, but
for now it is custom due to some specific style requirements.

We already have heredoc injection support, so this just extends it to also cover

Part of https://github.com/zed-industries/zed/issues/22606
Closes https://github.com/zed-industries/zed/issues/23509

When a user sees an odd notification from the language server like

<img width="508" alt="image"
src="https://github.com/user-attachments/assets/6f5ef1aa-0f09-4705-a02a-aaf81dd8620c"
/>

they usually dismiss that.

Zed uses channels to wait and handle user interactions with such
notifications, and, due to `?`, sends back
```json
{"jsonrpc":"2.0","id":1,"error":{"message":"receiving from an empty and closed channel"}}
```

which is not spec-compliant:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#window_showMessageRequest

> Response:
>
> * result: the selected
[MessageActionItem](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#messageActionItem)
| null if none got selected.
> * error: code and message set in case an exception happens during
showing a message.

Unfortunately, vtsls (and, potentially, others) crash if receive such
non-compliant requests, and do not get back.

After the fix, the message is correct:
```json
{"jsonrpc":"2.0","id":1,"result":null}
```

- Fixed vtsls crashing on notification dismiss

Part of https://github.com/zed-industries/zed/issues/22606

Before, `tsdk_path` for vtsls and typescript-language-server
unconditionally set a `tsdk`/`tsserver` property for the corresponding
language server, even if there were no such directory at all.
Instead, make the corresponding code to omit such property if it was not
found on the FS.

Release Notes:

- Fixed "The path /.../tsserver.js doesn't point to a valid tsserver
install. Falling back to bundled TypeScript version." pop-up appearing

Uses a newer `git2` version with
https://github.com/rust-lang/git2-rs/pull/1120 fix

Closes https://github.com/zed-industries/zed/issues/23453
