# doctor — idempotently wire up pre-commit framework into git's hook system.
# (.pre-commit-config.yaml at the repo root drives it.)
#
# Silent on success. If pre-commit is missing, prints a one-line note and
# exits 0 so callers (e.g. `make dev`) don't block on an optional tool.
# CI still runs the real linters.
#
# Quirks handled:
#   - pre-commit refuses to install when core.hooksPath is set, even when
#     it's set to the default location (a leftover from a stale setup).
#     Detect that exact case and unset it before installing.
#   - core.hooksPath is shared between the main repo and every worktree,
#     so a single install covers all of them.
