Release Notes:

- Added switch source/header action for clangd language server (fixes
[#12801](https://github.com/zed-industries/zed/issues/12801)).

Note: I'm new to both rust and this codebase. I started my
implementation by copying how rust analyzer's "expand macro" LSP
extension is implemented. I don't yet understand some of the code I
copied (mostly the way to get the `server_to_query` in `clangd_ext.rs`
and the whole proto implementation).

This has been bugging me for a while, because it meant I was stuck in
the collab panel when I accidentally navigated there via keyboard
shortcuts.

Now I can press esc and get out of that state.

collaboration panel.

### Pull Request Title
Introduce `max_output_tokens` Field for OpenAI Models


https://platform.deepseek.com/api-docs/news/news0725/#4-8k-max_tokens-betarelease-longer-possibilities

### Description
This commit introduces a new field `max_output_tokens` to the OpenAI
models, which allows specifying the maximum number of tokens that can be
generated in the output. This field is now integrated into the request
handling across multiple crates, ensuring that the output token limit is
respected during language model completions.

Changes include:
- Adding `max_output_tokens` to the `Custom` variant of the
`open_ai::Model` enum.
- Updating the `into_open_ai` method in `LanguageModelRequest` to accept
and use `max_output_tokens`.
- Modifying the `OpenAiLanguageModel` and `CloudLanguageModel`
implementations to pass `max_output_tokens` when converting requests.
- Ensuring that the `max_output_tokens` field is correctly serialized
and deserialized in relevant structures.

This enhancement provides more control over the output length of OpenAI
model responses, improving the flexibility and accuracy of language
model interactions.

### Changes
- Added `max_output_tokens` to the `Custom` variant of the
`open_ai::Model` enum.
- Updated the `into_open_ai` method in `LanguageModelRequest` to accept
and use `max_output_tokens`.
- Modified the `OpenAiLanguageModel` and `CloudLanguageModel`
implementations to pass `max_output_tokens` when converting requests.
- Ensured that the `max_output_tokens` field is correctly serialized and
deserialized in relevant structures.

### Checklist
- [x] Code compiles correctly.
- [x] All tests pass.
- [ ] Documentation has been updated accordingly.
- [ ] Additional tests have been added to cover new functionality.
- [ ] Relevant documentation has been updated or added.

### Release Notes

- Added `max_output_tokens` field to OpenAI models for controlling
output token length.

Closes #13579

A major painpoint in the Vim crate has been life-cycle management. We
used to have one global Vim instance that tried to track per-editor
state; this led to a number of subtle issues (e.g. #13579, the mode
indicator being global, and quick toggling between windows letting vim
mode's notion of the active editor get out of sync).

This PR changes the internal structure of the code so that there is now
one `Vim` instance per `Editor` (stored as an `Addon`); and the global
stuff is separated out. This fixes the above problems, and tidies up a
bunch of the mess in the codebase.

Release Notes:

* vim: Fixed accidental visual mode in project search and go to
references
([#13579](https://github.com/zed-industries/zed/issues/13579)).

This PR removes the docs for context servers.

This was previously using the value for the scrollbar border, instead of
the background.

I noticed this while trying out a new Zed theme.

Release Notes:

- Updated project panel scrollbar to respect the
`scrollbar.track.background` from the theme.

This PR allows configuring the intensity of code fade applied to unused
code (relates to #4785).

_Note: Right now I included it as a top level config which might be a
little out of place (but is easiest to instrument). Open for suggestions
on where else it would be better suited for._

_Note 2: I am unfamiliar with the codebase. Feel free to either close
this PR and re-implement in a better way or suggest high level changes
if I'm approaching anything wrong :)._

Release Notes:

- Added `unnecesary_code_fade` setting to control how strongly to fade
unused code.

PR #16501 introduced the new keybinding syntax for the docs and added
Javascript- and CSS-files to the theme to implement the change. These
new files were then referenced in the `book.toml` as well as added to
the `index.hbs`.

However, the manually added links to these assets in the
[`index.hbs`-file](https://github.com/zed-industries/zed/pull/16501/files#diff-8fde917c42f58487036335ccc9980f1467790fc1c257ec57a0c44bc5dfc3ef4f)
are neither needed nor resolvable:

src="https://github.com/user-attachments/assets/4a710b22-9274-4d27-96a8-6da59b0c9e68">


Therefore, this PR reverts the changes to the`index.hbs` - file, as the
correct links to the needed assets are inserted via the
`each`-directives from the `book.toml` respectively.

This PR can improve the UX when dropping a file that cannot be opened
into the workspace pane. Previously, nothing happened without any
messages when such error occurred, which could be awkward for users.
Additionally the pane was being split even though the file failed to
open.

Here's a screen recording demonstrating the previous/updated behavior:


https://github.com/user-attachments/assets/cfdf3488-9464-4568-b16a-9b87718bd729

Changes:

- It now displays an error message if a file cannot be opened.
- Updated the logic to first try to open the file. The pane splits only
if the file opening process is successful.

Release Notes:

- Improved error handling when opening files in the workspace pane. An
error message will now be displayed if the file cannot be opened.
- Fixed an issue where unnecessary pane splitting occurred when a file
fails to open.

- Fix links on assistant page to subpages
- Mention the configuration view in the `configuration.md` and document
more settings

This PR significantly expands the assistant documentation, breaking it
out into sections, adding examples and further documenting features.

This PR introduces a convention in docs for swapping keybindings for mac
vs linux:

`<kbd>cmd-enter|ctrl-enter</kbd>`

In the above example, the first will be shown for mac, the second for
linux or windows.

TODO:

- [ ] Fix table style (for `/assistant/configuration`)
- [x] Add script to swap keybindings based on platform
- It should take in this format: [`cmd-n` (mac)|`ctrl-n`(linux)] and
return just the correct binding for the viewer's platform.
- [ ] Add image/video assets (non-blocking)

Release Notes:

- Updated assistant documentation

This PR adds two Postgrest containers—one for the app database and one
for the LLM database—to the Docker Compose cluster.

Also fixed an issue where `postgres_app.conf` and `postgres_llm.conf`
had been switched.

This PR is a small refactor to remove the leading `_` for some free
variables, as this unintentionally marks them as unused to the compiler.

While the fields on the struct _are_ unused, the free variables should
participate in usage tracking, as we want to make sure they get stored
on the struct.

I had originally added the lightening bolt on every message and only
added the tooltip warning about editing prior messages on the first
anchor, but thought it looked too busy, so I settled on just annotating
the last anchor.

set the `ZED_CLOUD_PROVIDER_ADDITIONAL_MODELS_JSON` environment variable
