Git Hooks (prek)

prek is a Rust rewrite of pre-commit: same .pre-commit-config.yaml, same .pre-commit-hooks.yaml, no Python runtime required. Default to prek for new setups. A repo already on pre-commit keeps working — most commands below carry over unchanged, but not all; see "prek vs pre-commit CLI" before assuming a 1:1 mapping.
