Swap python-based pre-commit for prek via git-hooks.nix's `package` option. Two caveats worked around in `flake.nix`: - Upstream git-hooks.nix hardcodes `prek install` without `--git-dir`, which breaks in git worktrees where `.git` is a file. A shim injects `--git-dir` from `git rev-parse --git-common-dir` for install calls. - prek 0.3.9+ rejects empty `core.hooksPath` (git resolves "" to "."). Patch the generated shellHook to `--unset core.hooksPath` instead. The shim also passes `--overwrite` so reinstalls are silent. prek 0.3.8's `uninstall` subcommand rejects `--git-dir`, so the shim only adds the flag on `install`; the subsequent overwrite install supersedes any stale hook left behind.
