Closes https://github.com/zed-industries/zed/issues/33522

Turns out a bunch of Zed requests were not checking their capabilities
correctly, due to odd copy-paste and due to default that assumed that
the capabilities are met.

Adjust the code, which includes the document colors, add the test on the
colors case.

Release Notes:

- Fixed excessive document colors requests for unrelated files

Cherry-picked Fix blend alpha colors with editor background in inline
preview (#33513)

Closes #33505

Cherry-picked editor: Utilize `filter_text` from language server for
`filter_range` (#33155)

Closes #33106

Instead of directly using `filter_text` in `StringMatchCandidate`, which
yields better results for fuzzy matching but messes up with highlighting
letters in bold, as `positions` list generated by fuzzy crate are now of
`filter_text` and not `label` shown to the user.

This PR fixes it by keeping use of `filter_range` in
`StringMatchCandidate`, which is range w.r.t to `label` shown to user.
And actually generating this `filter_range` at source by using
`filter_range` if exists.

- [x] Tests

Release Notes:

- Fixed issue where incorrect letters are marked as bold in completions.

## Summary

This PR improves the workaround introduced in #33335 that handles cases
where the pinned tab count exceeds the actual tab count during workspace
deserialization.

## Problem

The original workaround in #33335 successfully prevented the panic but
had two issues:
1. **Console spam**: The warning message was logged repeatedly because
`self.pinned_tab_count` wasn't updated to match the actual tab count
2. **Auto-pinning behavior**: New tabs up until you exceed the old safe
tab count were automatically pinned after the workaround was triggered.

## Solution

Updates the defensive code to set `self.pinned_tab_count = tab_count`
when the mismatch is detected, ensuring:
- The warning is only logged once when encountered.
- New tabs behave normally (aren't auto-pinned)
- The workspace remains in a consistent state

This is an immediate fix for the workaround. I'll attempt to open up a
follow-up PR when i get the chance that will address the root cause by
implementing serialization for empty untitled tabs, as discussed in
#33342.

Cherry-picked debugger: Support passing custom arguments to debug
adapters (#33251)

Custom arguments replace any arguments that we normally pass to the DAP.
For interpreted languages, they are passed to the interpreter after the
DAP path or module. They can be combined with a custom binary, or you
can omit `dap.binary` and just customize the arguments to the DAPs we
download.

This doesn't take care of updating the extension API to support custom
arguments.

Release Notes:

- debugger: Implemented support for passing custom arguments to a debug
adapter binary using the `dap.args` setting.
- debugger: Fixed not being able to use the `dap` setting in
`.zed/settings.json`.

server (backport #33365)

Follow up to previous PRs:
- Return `true` in `supports_images` - v0 supports images already
- Rename model id to match the exact version of the model `v0-1.5-md`
(For now we do not expose `sm`/`lg` variants since they seem not to be
available via the API)
- Provide autocompletion in settings for using `vercel` as a `provider`

Release Notes:

- N/A

Follow up to #33292

Since Vercel's API is OpenAI compatible, we can reuse a bunch of code.

Release Notes:

- N/A

Vercel v0 is an OpenAI-compatible model, so this is mostly a dupe of the
OpenAI provider files with some adaptations for v0, including going
ahead and using the custom endpoint for the API URL field.

Release Notes:

- Added support for Vercel as a language model provider.

Cherry-picked agent: Do not send stale files notifications (#32974)

Removing it for two reasons:

1. We need a better implementation that doesn't hurt caching and doesn't
distracts the agent too much (see
https://github.com/zed-industries/zed/pull/32876 for more context)

2. Current insertion point of notifications doesn't play well with
Claude Thinking models (see

https://github.com/zed-industries/zed/issues/33000#issuecomment-2991709484)

I think we should get this code back in a form of a tool. But for now,
I'm dropping it to resolve recent issues.

Closes #33000

After much investigation, I have not been able to track down what is
causing [this
panic](https://github.com/zed-industries/zed/issues/33342). I'm clamping
the value for now, because a bug is better than a crash. Hopefully
someone finds reproduction steps, and I will implement a proper fix.

Cherry-picked Fix being unable to input a whitespace character in collab
channels filter (#33318)

Before, `space` was always causing a channel join.
Now it's less fluent, one has to press `ESC` to get the focus out of the
filter editor and then `space` starts joining the channel.

Release Notes:

We were seeing a bunch of errors in our backend when people were using
Claude models with thinking enabled.

In the logs we would see
> an error occurred while interacting with the Anthropic API:
invalid_request_error: messages.x.content.0.type: Expected `thinking` or
`redacted_thinking`, but found `text`. When `thinking` is enabled, a
final `assistant` message must start with a thinking block (preceeding
the lastmost set of `tool_use` and `tool_result` blocks). We recommend
you include thinking blocks from previous turns. To avoid this
requirement, disable `thinking`. Please consult our documentation at
https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking

However, this issue did not occur frequently and was not easily
reproducible. Turns out it was triggered by us not correctly handling
[Redacted Thinking
Blocks](https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#thinking-redaction).

I could constantly reproduce this issue by including this magic string:
`ANTHROPIC_MAGIC_STRING_TRIGGER_REDACTED_THINKING_46C9A13E193C177646C7398A98432ECCCE4C1253D5E2D82641AC0E52CC2876CB
` in the request, which forces `claude-3-7-sonnet` to emit redacted
thinking blocks (confusingly the magic string does not seem to be
working for `claude-sonnet-4`). As soon as we hit a tool call Anthropic
would return an error.

Thanks to @osyvokon for pointing me in the right direction 😄!


Release Notes:

- agent: Fixed an issue where Anthropic models would sometimes return an
error when thinking was enabled

Closes #31903

Release Notes:

- agent: Fix an issue where an error would occur when MCP servers

* Restore the ability to combine --diff with other path arguments
* Restore combining --diff with --wait

There is still one defect in the current handling of `--diff`: when Zed
is already open, we'll open the diff view in your current active zed
window. It would be better to search all of the open zed windows for any
window containing the diffed paths, but implementing that is a bit
complex. Currently, the logic for *picking* an existing zed window is
coupled to the logic for opening buffers in that window. I'd like to
decouple it, but I wanted to keep this change small, so that we hotfix
it to stable without too much risk.

Release Notes:

- Fixed a bug where the `--diff` CLI flag did not work with `--wait`

Release Notes:

- Fixed document colors not showing on file reopen

Co-authored-by: Kirill Bulatov <kirill@zed.dev>

Ran into this while adding support for Vercel v0s models:
- The timestamp seems to be returned in Milliseconds instead of seconds
so it breaks the bounds of `created: u32`. We did not use this field
anywhere so just decided to remove it
- Sometimes the `choices` field can be empty when the last chunk comes
in because it only contains `usage`

Release Notes:

- N/A

The `api_url` setting is one that most providers already support and can
be changed via the `settings.json`. We're adding the ability to change
it via the UI for OpenAI specifically so it can be more easily connected
to v0.

Release Notes:

- agent: Added ability to change the API base URL for OpenAI via the UI
