This PR updates ruff from 0.3.5 to 0.6.1.

Changelog

0.6.1

This is a hotfix release to address an issue with `ruff-pre-commit`. In v0.6,
Ruff changed its behavior to lint and format Jupyter notebooks by default;
however, due to an oversight, these files were still excluded by default if
Ruff was run via pre-commit, leading to inconsistent behavior.
This has [now been fixed](https://github.com/astral-sh/ruff-pre-commit/pull/96).

Preview features

- \[`fastapi`\] Implement `fast-api-unused-path-parameter` (`FAST003`) ([12638](https://github.com/astral-sh/ruff/pull/12638))

Rule changes

- \[`pylint`\] Rename `too-many-positional` to `too-many-positional-arguments` (`R0917`) ([12905](https://github.com/astral-sh/ruff/pull/12905))

Server

- Fix crash when applying "fix-all" code-action to notebook cells ([12929](https://github.com/astral-sh/ruff/pull/12929))

Other changes

- \[`flake8-naming`\]: Respect import conventions (`N817`) ([12922](https://github.com/astral-sh/ruff/pull/12922))

0.6.0

- Detect imports in `src` layouts by default for `isort` rules ([12848](https://github.com/astral-sh/ruff/pull/12848))

- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments ([12838](https://github.com/astral-sh/ruff/pull/12838)).

- Lint and format Jupyter Notebook by default ([12878](https://github.com/astral-sh/ruff/pull/12878)).

 You can disable specific rules for notebooks using [`per-file-ignores`](https://docs.astral.sh/ruff/settings/#lint_per-file-ignores):

 toml
 [tool.ruff.lint.per-file-ignores]
 "*.ipynb" = ["E501"]  disable line-too-long in notebooks
 

 If you'd prefer to either only lint or only format Jupyter Notebook files, you can use the
 section-specific `exclude` option to do so. For example, the following would only lint Jupyter
 Notebook files and not format them:

 toml
 [tool.ruff.format]
 exclude = ["*.ipynb"]
 

 And, conversely, the following would only format Jupyter Notebook files and not lint them:

 toml
 [tool.ruff.lint]
 exclude = ["*.ipynb"]
 

 You can completely disable Jupyter Notebook support by updating the [`extend-exclude`](https://docs.astral.sh/ruff/settings/#extend-exclude) setting:

 toml
 [tool.ruff]
 extend-exclude = ["*.ipynb"]

0.4.5

Ruff's language server is now in Beta

`v0.4.5` marks the official Beta release of `ruff server`, an integrated language server built into Ruff.
`ruff server` supports the same feature set as `ruff-lsp`, powering linting, formatting, and
code fixes in Ruff's editor integrations -- but with superior performance and
no installation required. We'd love your feedback!

You can enable `ruff server` in the [VS Code extension](https://github.com/astral-sh/ruff-vscode?tab=readme-ov-file#enabling-the-rust-based-language-server) today.

0.4.0

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](https://astral.sh/blog/ruff-v0.4.0) for more details!

See [10036](https://github.com/astral-sh/ruff/pull/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](https://microsoft.github.io/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](https://github.com/astral-sh/ruff-lsp)
-- 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](https://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).
