Update pre-commit to monorepo

[dimaqq]

We've switched to monorepo, but pre-commit got left behind.

Today it looks like:

    - repo: https://github.com/astral-sh/ruff-pre-commit
      rev: v0.11.2
      hooks:
        - id: ruff
E         args: [ --preview ] # E: too many spaces inside brackets
        - id: ruff-format
E         args: [ --preview ] # E: too many spaces inside brackets
    # Spellcheck the code.
    - repo: https://github.com/codespell-project/codespell
      rev: v2.4.1
      hooks:
E     - id: codespell # E: wrong indentation: expected 6 but found 4
        additional_dependencies:
          - tomli
    # Check workflow security.

And it could be something like:

  - repo: local
    hooks:
      - id: ruff
        name: ruff (uv)
        entry: uv run -- ruff check --preview
        language: system
        types: [python]

      - id: pyright
        name: pyright (uv)
        entry: uv run -- pyright
        language: system
        types: [python]
