For long threads we will spend more and more time cloning the messages
just to save them to the database, as we need a copy of everything to do
so asynchronously. Messages are really expensive to clone though and we
accumulate a lot of them really fast, so even for smaller threads we
start seeing pauses in the millisecond range. The fix to this is fairly
simple though, we never mutate the messages once pushed to the vec, so
just Arc them.
This PR also slightly changes `UserMessage` to be a bit faster to clone
as well.
Release Notes:
- Fixed a cause of stutters when interacting with the agent
Follow-up to #49292:
- **Bug fix in `push_any_of_constraint`**: when both an `anyOf` and a
non-empty `allOf` were already present at the same level, the existing
`anyOf` was silently dropped. Now it's always preserved.
- **Canonical OpenAPI nullability**: collapse `{nullable: true}`-only
entries out of `anyOf` onto the parent so `anyOf: [{type: "string"},
{type: "null"}]` becomes `{type: "string", nullable: true}` (the form
Gemini actually expects) instead of `anyOf: [{type: "string"},
{nullable: true}]`.
- **Compile-time path consistency**: route `ToJsonSchemaSubsetTransform`
through the same `convert_null_in_types_to_nullable` helper so
Rust-defined tools using `Option<T>` also keep nullability on Gemini,
instead of silently truncating to the non-null type.
- Drop an unnecessary clone in `push_any_of_constraint` and simplify
`convert_types_to_any_of_defs`.
- Add a small `obj()` test helper and a regression test for the `anyOf +
allOf + multi-type` case.
Release Notes:
- Fixed `Option<T>` tool parameters being sent to Gemini without their
nullability, and fixed tool schemas with `anyOf` + `allOf` losing
constraints during the OpenAPI 3.0 conversion

Release Notes:
- gemini: Fixed an issue with MCP servers specifying tools with specific
schemas
When toggling fast mode, the setting is now written to `settings.json`
under `agent.default_model.speed`, so new threads start with the same
speed. This follows the same pattern as `enable_thinking` and `effort`.
The `speed` field uses the existing `Speed` enum (`"fast"` /
`"standard"`) rather than a boolean, to leave room for future speed
tiers.
Example settings:
```json
{
"agent": {
"default_model": {
"provider": "zed.dev",
"model": "claude-sonnet-4",
"speed": "fast"
}
}
}
```

- `language_model` no longer depends on provider-specific crates such as
`anthropic` and `open_ai` (inverted dependency)
- `language_model_core` was extracted from `language_model` which
contains the types for the provider-specific crates to convert to/from.
- `gpui::SharedString` has been extracted into its own crate (still
exposed by `gpui`), so `language_model_core` and provider API crates
don't have to depend on `gpui`.
- Removes some unnecessary `&'static str` | `SharedString` -> `String`
-> `SharedString` conversions across the codebase.
- Extracts the core logic of the cloud `LanguageModelProvider` into its
own crate with simpler dependencies.
