A new, hand-written parser

Ruff's new parser is >2x faster, which translates to a 20-40% speedup for all linting and formatting invocations.
There's a lot to say about this exciting change, so check out the blog post for more details!

See #​10036 for implementation details.

A new language server in Rust

With this release, we also want to highlight our new language server. ruff server is a Rust-powered language
server that comes built-in with Ruff. It can be used with any editor that supports the Language Server Protocol (LSP).
It uses a multi-threaded, lock-free architecture inspired by rust-analyzer and it will open the door for a lot
of exciting features. It’s also faster than our previous Python-based language server
-- but you probably guessed that already.

ruff server is only in alpha, but it has a lot of features that you can try out today:

• Lints Python files automatically and shows quick-fixes when available
• Formats Python files, with support for range formatting
• Comes with commands for quickly performing actions: ruff.applyAutofix, ruff.applyFormat, and ruff.applyOrganizeImports
• Supports source.fixAll and source.organizeImports source actions
• Automatically reloads your project configuration when you change it

To setup ruff server with your editor, refer to the README.md.
