pre-commit-hooks.nix

Wires pre-commit hooks directly into Nix development shells (`nix develop`) and CI checks (`nix flake check`), ensuring tooling consistency across environments as demonstrated in the flake example.

Pre-builds all hook tooling in Nix to avoid latency from naive `nix-shell` calls on each commit, a key feature highlighted in the README to reduce overhead.

Includes built-in hooks for dozens of languages and tools like nixfmt, black, and shellcheck, reducing manual configuration effort, with a comprehensive list provided.

Supports defining project-specific hooks with the same schema as pre-defined ones, allowing tailored checks, as shown in the custom hook example with settings like `entry` and `stages`.
