Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.

## Changes

- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.

## Benefits

- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.

Follows Rust guidelines; run `./script/clippy` for verification.

- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

This PR cleans up some emitted events around the codebase. These events
are either never emitted or never listened for.

It seems better to re-implement these at some point should they again be
needed - this ensures that they will actually be fired in the cases
where they are needed as opposed to being there and getting unreliable
and stale (which is already the case for the majority of the events
removed here).

Lastly, this ensures the `CapabilitiesChanged` event is not fired too
often.

Added schemars annotations to generate inline enums instead of
references ($ref) in the JSON schema passed to LLMs.

Concerns :
- "timezeone" parameter for "now" tool function
- "mode" parameter for "edit_file" tool function

Should be the same for futures tools/functions enums. This is easier for
LLMs to understand the schema since many of them don't use JSON
references correctly.

Tested with :
- local GPT-OSS-120b with llama.cpp server (openai compatible)
- remote Claude Sonnet 4.0 with Zed pro subscription

Thanks in advance for the merge.
(notice this is my first PR ever on Github, I hope I'm doing things
well, please let me know if you have any comment - edit: just noticed my
username/email were not correctly setup on my local git, sorry, it's
been 5 years I've not used git)

Closes #37389

Release Notes:

- agent: Improve "now" and "edit_file" tool schemas to work with more
models.

The example was still showing how we used to setup openai compatible
providers, but that format should only be used for changing the url for
your actual OpenAI provider.

If you are doing a compatible provider, it should be using the new
format.

Closes #37093

Closes #37289

The current implementation has a problem. The **`from_id` method** in
the Anthropic crate works well for predefined models, but not for custom
models that are defined in the settings. This is because it fallbacks to
using default beta headers, which are incorrect for custom models.

The issue is that the model instance for custom models lives within the
`language_models` provider, so I've updated the **`stream_completion`**
method to explicitly accept beta headers from its caller. Now, the beta
headers are passed from the `language_models` provider all the way to
`anthropic.stream_completion`, which resolves the issue.

Release Notes:

- Fixed a bug where extra_beta_headers defined in settings for Anthropic
custom models were being ignored.

We don’t know the background color behind a non-opaque editor, so we
should skip contrast correction in that case. This prevents
single-editor mode (which is always transparent) from showing weird text
colors when text is selected.

We can’t account for the actual background during contrast correction
because we compute contrast outside gpui, while the actual color
blending happens inside gpui during drawing.

Closes https://github.com/zed-industries/zed/issues/37144

Adjusts `editor::DeleteToPreviousWordStart`,
`editor::DeleteToNextWordEnd`, `editor::DeleteToNextSubwordEnd` and
`editor::DeleteToPreviousSubwordStart` actions to

* take whitespace sequences with length >= 2 into account and stop after
removing them (whilst movement would also include the word after such
sequences)

* take current language's brackets into account and stop after removing
the text before them

The latter is configurable and can be disabled with `"ignore_brackets":
true` parameter in the action.

Release Notes:

- Improved word deletions to consider whitespace sequences and brackets
by default

With `reveal_stragegy=always` + `reveal_target=center`,
`TerminalPanel::spawn_task` activates & focuses the pane of the task.
This works fine in the terminal pane but doesn't for
`reveal_target=center`.

Please note: I'm not verified familiar with the architecture and
internal APIs of zed. If there's a better way or if this fix is a bad
idea, I'm fine with adapting this 😃

### First issue

In the scenario where you have an API key configured in Zed and you run
`/logout`, clicking on `Use Anthropic API Key` would show `Method not
implemented`.

This happened because we were only intercepting the `Use Anthropic API
Key` click if the provider was NOT authenticated, which would not be the
case when the user has an API key set.

### Second issue

When clicking on `Reset API Key` the modal would be dismissed even
though you picked no Authentication Method (which means you still would
be unauthenticated)

When the first visible worktree is a single-file worktree, we would
previously try to use the absolute path of that file as the root
directory for external agents, causing an error. This PR changes how we
handle this situation: we'll use the root of the first non-single-file
visible worktree if there are any, and if there are none, the parent
directory of the first single-file visible worktree.

- Allowed wrapping markdown text into `*` by selecting text and writing

The only warnings remaining are links to private modules/items, but I
lack knowledge to work out if the referenced modules/items should be
made public, or if the links should be rewritten into exposed
traits/items.

Links to associated items such as trait implementations have to be
written using full markdown format such as:

... [[ `App::update_global` ]](( BorrowAppContext::update_global ))

This is due to https://github.com/rust-lang/rust/issues/74563 which
sadly prohibits fully-qualified syntax:
