Pull the hook logic into a reusable githook library package so tailscale/corp can share it via a thin wrapper main instead of keeping a forked copy in sync. The install flow also changes: a wrapper scripts now build the binary and reinstall the git hooks. Pulling new shared code no longer requires re-running the installer. Updates tailscale/corp#39860 Change-Id: I4d606d11c8c883015c190c54e3387a7f9fe4dd32 Signed-off-by: Fernando Serboncini <fserb@tailscale.com>
