    # The installed git hooks run later under Git, outside this just/mise environment,
    # so they need to be told how to find their tooling:
    #
    # - PREK_HOME keeps prek's cache under var/prek instead of a global home dir.
    # - MISE_DATA_DIR / MISE_TRUSTED_CONFIG_PATHS make mise resolve against this project's
    #   own data directory. Without them mise falls back to the global one and silently
    #   installs a second copy of the tool there.
    # - prek bakes the full path of the currently installed version into the hook
    #   (var/mise/installs/prek/<version>/...), which stops working as soon as the pinned
    #   version changes or old versions are pruned. Pointing at mise's shim instead makes
    #   the hook resolve whatever mise.toml pins, at the time it runs.
    #
    # Which hook files prek installs depends on `default_install_hook_types` in
    # .pre-commit-config.yaml, so patch every hook file that prek generated.
