Summary

This is a follow-up to #10984 that implements configuration resolution for editor configuration. By 'editor configuration', I'm referring to the client settings that correspond to Ruff configuration/options, like preview, select, and so on. These will be combined with 'project configuration' (configuration taken from project files such as pyproject.toml) to generate the final linter and formatter settings used by RuffSettings. Editor configuration takes priority over project configuration.

In a follow-up pull request, I'll implement a new client setting that allows project configuration to override editor configuration, as per this issue.

Review guide

The first commit, e38966d, is just doing re-arrangement so that we can pass the right things to RuffSettings::resolve. The actual resolution logic is in the second commit, 0eec9ee. It might help to look at these comments individually since the diff is rather messy.

Test Plan

For the settings to show up in VS Code, you'll need to checkout this branch: astral-sh/ruff-vscode#456.

To test that the resolution for a specific setting works as expected, run through the following scenarios, setting it in project and editor configuration as needed:

Set in project configuration? Set in editor configuration? Expected Outcome
No No The editor should behave as if the setting was set to its default value.
Yes No The editor should behave as if the setting was set to the value in project configuration.
No Yes The editor should behave as if the setting was set to the value in editor configuration.
Yes Yes (but distinctive from project configuration) The editor should behave as if the setting was set to the value in editor configuration.

An exception to this is extendSelect, which does not have an analog in TOML configuration. Instead, you should verify that extendSelect amends the select setting. If select is set in both editor and project configuration, extendSelect will only append to the select value in editor configuration, so make sure to un-set it there if you're testing extendSelect with select in project configuration.

I'm working on adding some snapshot tests, but the PR should be ready for review regardless.

## Summary

This is a follow-up to astral-sh/ruff#10984,
which implemented support for common Ruff configuration options in
client settings. This PR exposes these new settings in the extension
configuration.

These settings are different from other extension settings, because they
don't have default values. Instead, if the user does not set them, they
will be sent as `null`, and the server will use project configuration
instead.

At the moment, `ruff server` does not actually resolve these settings
yet - settings resolution is introduced in
astral-sh/ruff#11062, which means that you'll
need to work from that branch to test this PR (and vice-versa).

## Test Plan

See the test plan in astral-sh/ruff#11062.

…er editor configuration (#11086)

## Summary

This is intended to address
astral-sh/ruff-vscode#425, and is a follow-up
to #11062.

A new client setting is now supported by the server,
`prioritizeFileConfiguration`. This is a boolean setting (default:
`false`) that, if set to `true`, will instruct the configuration
resolver to prioritize file configuration (aka discovered TOML files)
over configuration passed in by the editor.

A corresponding extension PR has been opened, which makes this setting
available for VS Code:
astral-sh/ruff-vscode#457.

## Test Plan

To test this with VS Code, you'll need to check out [the VS Code
PR](astral-sh/ruff-vscode#457) that adds this
setting.

The test process is similar to
#11062, but in scenarios where the
editor configuration would take priority over file configuration, file
configuration should take priority.
