Note

Switches to Ruff + pre-commit and applies repository-wide lint/style updates (modern typing, formatting), with minor non-functional refactors and doc cleanups.

• Tooling/Linting:
  • Migrate to Ruff-based linting and pre-commit: add pre-commit-hooks, switch to ruff-check/ruff-format, update versions; remove Black config/dependency; update Ruff config (line length, target version, rules).
• Codebase-wide style updates:
  • Apply lint fixes across modules: modern typing (| None, collections.abc), f-strings, simplified asserts, formatting/line-length, minor refactors without behavior changes.
• Docs:
  • Whitespace/formatting cleanups in markdown and JS/CSS snippets.
