## Summary
PR adding support for it in the VS Code extension:
https://github.com/astral-sh/ty-vscode/pull/36
This PR adds support for `python.ty.disableLanguageServices` to the ty
language server by accepting this as server setting.
This has the same issue as https://github.com/astral-sh/ty/issues/282 in
that it only works when configured globally. Fixing that requires
support for multiple workspaces in the server itself.
I also went ahead and did a similar refactor as the Ruff server to use
"Options" and "Settings" to keep the code consistent although the
combine functionality doesn't exists yet because workspace settings
isn't supported in the ty server.
## Test Plan
Refer to https://github.com/astral-sh/ty-vscode/pull/36 for the test
demo.
Specifically, this PR reverts "Make completions an opt-in LSP feature
(#17921)",
corresponding to commit 51e2effd2d.
In practice, this means you don't need to opt into completions working
by enabling experimental features. i.e., I was able to remove this from
my LSP configuration:
```
"experimental": {
"completions": {
"enable": true
}
},
```
There's still a lot of work left to do to make completions awesome, but
I think it's in a state where it would be useful to get real user
feedback. It's also meaningfully using ty to provide completions that
use type information.

## Summary
This PR moves the diagnostics API for the language server out from the
request handler module to the diagnostics API module.
This is in preparation to add support for publishing diagnostics.
## Summary
This PR updates the language server to avoid panicking when there are
multiple workspace folders passed during initialization. The server
currently picks up the first workspace folder and provides a warning and
a log message.

## Summary
This PR is a first step toward integration of the new `Diagnostic` type
into ruff. There are two main changes:
- A new `UnifiedFile` enum wrapping `File` for red-knot and a
`SourceFile` for ruff
- ruff's `Message::SyntaxError` variant is now a `Diagnostic` instead of
a `SyntaxErrorMessage`
The second of these changes was mostly just a proof of concept for the
first, and it went pretty smoothly. Converting `DiagnosticMessage`s will
be most of the work in replacing `Message` entirely.
## Test Plan
Existing tests, which show no changes.

## Summary
We now expect the client to send initialization options to opt-in to
experimental (but LSP-standardized) features, like completion support.
Specifically, the client should set `"experimental.completions.enable":
true`.
Closes https://github.com/astral-sh/ty/issues/74.
