Cherry-picked Fix more inlay/excerpt race conditions (#28914)

Closes #ISSUE

The UI was mistakenly using the cumulative token usage for the token
counter. It will now display the last request token count, plus an
estimation of the tokens in the message editor and context entries that
haven't been sent yet.

Additionally, when the user edits a message, we'll display the actual
token count up to it and estimate the tokens in the new message.

Note: We don't currently estimate the delta when switching profiles. In
the future, we want to use the count tokens API to measure every part of
the request and display a breakdown.

Release Notes:

- agent: Made the token count more accurate and added back estimation of
used tokens as you type and add context.

Release Notes:

- Preview: Removed the layout button from the title bar. The
`bottom_dock_layout` setting still functions.
- Added a setting, `bottom_dock_layout`, for controlling the
relationship between the bottom dock and the left and right docks.

Make fuzzy search in @-mention match paths and context kinds as well
(e.g., typing "sym" should let me select the "Symbols" label, as opposed
to just paths)

Release Notes:

- agent: Improve fuzzy-matching when using @mentions

Release Notes:

- agent: Added a menu item to open the Prompt Library from the panel's
dropdown menu on the top right.

users later

We register buffers with language servers lazily when in multi-buffer
(when the excerpt is interacted with); this does not account for inlay
hints, of which a mere presence on a screen is enough to query a
language server with a path it does not recognize. This posed a problem
with typescript-language-server, which sent a notification to the user
whenever they had a multibuffer open with inlay hints enabled.

Closes #ISSUE

Release Notes:

- Fixed annoying pop-up with typescript-language-server that happened in
multi-buffers with inlay hints enabled.

This PR adds a debug panel context menu that will allow a user to select
which debug session items are visible.

The context menu will add to the pane that was right clicked on.

The implementation of commondir discovery in #27885 was wrong, most
significantly for submodules but also for worktrees in rarer cases. The
correct procedure, implemented in this PR, is:

> If `.git` is a file, look at the `gitdir` it points to. If that
directory has a file called `commondir`, read that file to find the
commondir. (This is what happens for worktrees.) Otherwise, the
commondir is the same as the gitdir. (This is what happens for
submodules.)

The author of Rails' minitest integration
[recommended](https://github.com/zed-extensions/ruby/issues/56#issuecomment-2795010202)
using the test name rather than line number.

This solves the problem in
https://github.com/zed-extensions/ruby/issues/56.

Note that everything is within `command`. I first tried using `args`:

```json
{
  "command": "bin/rails",
  "args": ["test", "$ZED_RELATIVE_FILE -n /$ZED_SYMBOL/"],
  "tags": ["ruby-test"]
}
```
but minitest receives this as:

```
Run options: -n "/\"foo bar\"/" --seed 31855
```

which doesn't match due to the escaping.

Closes #28782 

The linked template path was updated in #28250. This PR also adds the
change to the zed action.

Since the issue template link was also referenced in workspace, I
updated that occurrence to use the `FileBugReport` action instead. For
that, I had to move the action to `zed_actions`. However, with this
change only one link has to be updated and any database related errors
will have the zed version specs attached to them automatically.

Release Notes:

- Fixed an issue where the `file bug report` action would redirect to an
outdated URL.

Closes #27406

We've been seeing `test_no_duplicated_completion_requests` fail randomly
with the error "condition timed out".

But it's always failing on MacOS, and MacOS sets a shorter timeout of
100ms, compared to 1s from other platforms, this PR increases MacOS's
timeout to match other platforms'.

This PR adds a new `subscription_usages` table to the LLM database.

We'll use this table to track usage by subscribers.

Records will be looked up using `(user_id, period_start_at,
period_end_at)` to find the record for a user's current subscription
period.

We ran the locator after configuring the debugger binary which cause the
binary to never use the configuration from the cargo locator. This PR
fixes this by correcting the order of configuration.

These steps solved audio issues on my system (Tuxedo OS), but should be
applicable to any PipeWire/PulseAudio system that has more than one
audio interface.

I suspect that enabling `rtc_use_pipewire` in [LiveKit SDK](https://github.com/livekit/rust-sdks/blob/0773bcec4e24812b382e71166b2ab359bf1a9384/webrtc-sys/libwebrtc/build_linux.sh#L105C1-L105C27)
could help as well, but I haven't tried it.
