The goal of this PR is to support tool calls using ollama. A lot of the
serialization work was done in
https://github.com/zed-industries/zed/pull/15803 however the abstraction
over language models always disables tools.

## Changelog:

- Use `serde_json::Value` inside `OllamaFunctionCall` just as it's used
in `OllamaFunctionCall`. This fixes deserialization of ollama tool
calls.
- Added deserialization tests using json from official ollama api docs.
- Fetch model capabilities during model enumeration from ollama provider
- Added `supports_tools` setting to manually configure if a model
supports tools

## TODO:

- [x] Fix tool call serialization/deserialization
- [x] Fetch model capabilities from ollama api
- [x] Add tests for parsing model capabilities 
- [ ] Documentation for `supports_tools` field for ollama language model
config
- [ ] Convert between generic language model types
- [x] Pass tools to ollama

This PR adds prompt usage information, and easy access to managing your
account, to the agent overflow menu:

![CleanShot 2025-05-05 at 10 04
20@2x](https://github.com/user-attachments/assets/337a1a0b-6f71-49a0-9fe7-4fbf2ec1fc27)

Currently this UI will only show after making a request. We'll work on
eagerly getting the usage info later.

Release Notes:

- Added current prompt usage information to the agent menu (`...`) for
Zed AI users

Release Notes:

- Improved display of diffs when the agent rewrites a file from scratch.

Bypass our terminal subsystem and just run a shell in a pty.

- [x] make sure we use the same working directory
- [x] strip control chars from the pty output (?)
- [x] tests

Otherwise the panel keeps scrolling as the new token comes in and it is
almost impossible to keep the scroll position in the right place.

Also, if the user is editing, it is likely that the current generated
tokens will need to be regenerated anyway, so we may as well stop the
current progress.

Release Notes:

- Agent Beta: Stop generating tokens if previous messages are edited.

Github Copilot currently supports following models for agent mode with
tool calls. Currently we are only supporting anthropic models and not
openai and gemini. This PR add support for the openai models. I have
tested it and it works for all of them. For gemini models it seems there
is a issues from copilot side so not adding that in this PR as enabling
gemini model breaks it in the ask mode as well.

Kinda feel like the way that makes the most sense to sort profiles in
the dropdown is by relevance/impact. "Write" is the default profile and
contains all built-in tools turned on by default, thus it should be the
first. "Ask" contains read-only tools, one step down from Write. And
"Manual" is totally empty, the least "powerful" profile, thus the last.

This is purely a cosmetic change, renamed `@rules` to `@rule` which
unifies the @mention experience (for files, threads etc. we also use
`@file`, `@thread` not `@files`, `@thread`). Would also make sense to
rename the rules picker to rule picker, but i do not wanna introduce
conflicts just for the purpose of re-naming.

I also introduced a new eval to prove the encouragement actually makes a

Release Notes:

- Introduced the ability to follow the agent around as it reads and
edits files.

Now instead of the model hallucinating tool calls, we get requests for
more context:

(e.g. in `Manual` profile).

Closes #29836

The agent diff toolbar item was causing the editor toolbar to show even
when all the other elements were disabled via settings.

This PR fixes this by setting the location to
`ToolbarItemLocation::Hidden` in the states where it shouldn't show.

It also adds a new a `toolbar.agent_review` setting to hide the agent
review buttons altogether. However, if the other toolbar elements are
hidden and the file isn't under review, the editor toolbar will still be
hidden. So you only need to set this to `false` if you don't want them
to show up even under agent review.

Release Notes:

- N/A

Release Notes:

- agent: Add the `single_file_review` setting to the UI

This PR adds a singular constant that controls the Agent-related feature
flags.

This way we can tweak this one value when we're ready to build the final
build for the launch.

Release Notes:

This sets us up to display queue position information to the user, once
our language model backend is updated to support request queuing.

The JSON returned by the LLM backend will need to look like this:

{"queue": {"status": "started"}}
{"event": {"THE_UPSTREAM_MODEL_PROVIDER_EVENT": "..."}}

Previously, the assistant panel width was not persisted across sessions.
This meant that upon restarting the Zed editor, the panel would revert
to its default size, disrupting the user's preferred layout.

This pull request introduces persistence for the assistant panel width.
The width is now saved to the key-value store when the editor is closed
and restored on startup, ensuring a consistent UI experience across
different sessions.

Release Notes:

- agent: Add assistant panel width persistence
