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.

This reverts commit 40199266b6634cc3165f3842abae1d562ef4dcca.

The issue with the commit is: ContentMask<Pixels>::intersect is doing
intersection of corner radii which makes inner containers use the max
corner radius out of all the parents when it should be more complex to
correctly clip children (clip sorting..?)

When listing previously-downloaded versions of an external agent, don't
try to use any downloads that are missing the agent entrypoint
(indicating that they're corrupt/unusable), and delete those versions,
so that we can attempt to download the latest version again.

agent server entrypoint or root directory not existing.

Adds a test that checks that all settings have default values in

editor they will be added to the test as well.

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 `*`

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:

... [[ `<App as BorrowAppContext>::update_global` ]]

Hi! As part of https://github.com/zed-extensions/ruby/issues/162 we
would like to rename HTML/ERB to HTML+ERB since it is more syntactically
correct to treat such language as ERB on top of HTML rather than HTML or
ERB.

To keep the user experience intact, we outlined the prerequisites in the
linked issue. This is the first PR that adds the HTML+ERB language name
to the list of enabled languages for the Emmet extension. We will do the
same for the Tailwind configuration in the Zed codebase. Once the new
versions of Emmet and Zed are released, we will merge the pull request
in the Ruby extension repository and release the updated version. After
that, we will remove the old HTML/ERB and YAML/ERB languages. Let me
know if that sounds good. Thanks!
