This PR fixes an issue where we would redirect the user's browser to the
sign-in success page even if the OAuth callback was malformed.

We now parse the OAuth callback parameters from the query string and
only redirect to the sign-in success page when they are valid.

Release Notes:

- Updated the sign-in flow to not show the sign-in success page
prematurely.

This will be used to improve the clarity of the git clone UI

- Correctly pre-allocate `Vec` when deserializing regexes
- Simplify manual `Vec::with_capacity` calls by using `Iterator::unzip`
- Collect directly into `Arc<[T]>` (uses `Vec` internally anyway, but
simplifies code)
- Remove unnecessary `LazyLock` around Atomics by not using const
incompatible `Default` for initialization.

In Vim mode, `ap` text object (used in `vap`, `dap`, `cap`) was
selecting multiple paragraphs when soft wrap was enabled. The bug was
caused by using DisplayRow coordinates for arithmetic instead of buffer
row coordinates in the paragraph boundary calculation.

Fix by converting to buffer coordinates before arithmetic, then back to
display coordinates for the final result.

The view was cancelling the generation, but `AcpThread` already handles
that, so we removed that extra code and fixed a bug where an update from
the first user message would appear after the second one.

Closes #36218

Release Notes:

- Debugger: Python debugger installation no longer assumes that pip is
available in global Python installation

When a turn ends and the checkpoint is updated, `AcpThread` emits
`EntryUpdated` with the index of the user message. This was causing the
message editor to be recreated and, therefore, lose focus.

Prior to https://github.com/zed-industries/zed/pull/34564 as well as
https://github.com/zed-industries/zed/pull/26893, we would have cases
where editors would be scrollable even if `soft_wrap` was set to
`editor_width`. This has regressed and improved quite a few times back
and forth. The issue was only within the editor code, the code for the
wrap map was functioning and tested properly.

Hence, this PR adds two tests to the editor rendering code in an effort
to ensure that we maintain the current correct behavior.

Closes https://github.com/zed-industries/zed/issues/11780

While auto indentation is generally nice to have, there are cases where
it is currently just not good enough for some languages (e.g. Haskell)
or users just straight up do not want their editor to auto indent for
them. Hence, this PR adds the possibilty to disable auto indentation for
either all language or on a per-language basis. Manual invocation via
the `editor: auto indent` action will continue to work.

Also takes a similar approach as
https://github.com/zed-industries/zed/pull/31569 to ensure performance
is fine for larger multicursor edits.

Release Notes:

- Added the possibility to configure auto indentation for all languages
and per language. Add `"auto_indent": false"` to your settings or
desired language to disable the feature.

Closes #36247

Fix a panic when padding inlay hints if the last character is a
multi-byte character. Regressed in
https://github.com/zed-industries/zed/pull/35786.

Release Notes:

- Fixed a crash that could occur when an inlay hint ended with `...`.

Follow up to #36278 to ensure this bug is actually fixed. Also fixes
this on two layers and adds a test for the lower layer, as we cannot
properly test it in the UI.

Furthermore, this improves the error message to show some more context
and ensures the status toast is actually only shown when the keybind was
successfully updated: Before, we would show the success toast whilst
also showing an error in the editor.

Lastly, this also fixes some issues with the status toast (and
animations) where no status toast or no animation would show in certain
scenarios.

This adds a context menu to buffer headers mimicking that of pane tabs,
notably being able to copy the relative and absolute paths of the buffer
as well as opening a terminal in the parent.

Confusingly prior to this right clicking a buffer header used to open
the context menu of the underlying editor.

In the case where commit message was suggested based on single tracked
entry, this PR adds a clause to the condition to ensure there are no
staged entries.

Release Notes:

- Fixed commit message suggestion when there is one unstaged tracked
file, but multiple untracked files are staged.

- **WIP: reorganize dispositions**
- **Introduce a LocalToolchainStore trait and use it for LspAdapter
methods**

Closes #35782
Closes #27331

Release Notes:

- Python: Improved propagation of a selected virtual environment into
the LSP configuration. This should the make all language-related
features such as Go to definition or Find all references more reliable.

### TL;DR
* Adds `capabilities` configuration for OpenAI-compatible models
* Relates to
https://github.com/zed-industries/zed/issues/36215#issuecomment-3193920491

### Summary
This PR introduces support for configuring model capabilities for
OpenAI-compatible language models. The implementation addresses the
issue that not all OpenAI-compatible APIs support the same features -
for example, Cerebras' API explicitly does not support
`parallel_tool_calls` as documented in their [OpenAI compatibility
guide](https://inference-docs.cerebras.ai/resources/openai#currently-unsupported-openai-features).

### Changes

1. **Model Capabilities Structure**:
- Added `ModelCapabilityToggles` struct for UI representation with
boolean toggle states
- Implemented proper parsing of capability toggles into
`ModelCapabilities`

2. **UI Updates**:
- Modified the "Add LLM Provider" modal to include checkboxes for each
capability
- Each OpenAI-compatible model can now be configured with its specific
capabilities through the UI

3. **Configuration File Structure**:
- Updated the settings schema to support a `capabilities` object for
each `openai_compatible` model
- Each capability (`tools`, `images`, `parallel_tool_calls`,
`prompt_cache_key`) can be individually specified per model

### Example Configuration

```json
{
  "openai_compatible": {
    "Cerebras": {
      "api_url": "https://api.cerebras.ai/v1",
      "available_models": [
        {
          "name": "gpt-oss-120b",
          "max_tokens": 131000,
          "capabilities": {
            "tools": true,
            "images": false,
            "parallel_tool_calls": false,
            "prompt_cache_key": false
          }
        }
      ]
    }
  }
}
```

### Tests Added

- Added tests to verify default capability values are correctly applied
- Added tests to verify that deselected toggles are properly parsed as
`false`
- Added tests to verify that mixed capability selections work correctly

Thanks to @osyvokon for the desired `capabilities` configuration
structure!


Release Notes:

- OpenAI-compatible models now have configurable capabilities (#36370;
thanks @calesennett)

Fix zero-sized texture creation that triggers a SIGABRT in the Metal
renderer. Not sure why this happens yet, but it likely occurs when
`native_window.contentView()` returns a zero `NSSize` during initial
window creation, before the view size is computed.
