Move HOOK_VERSION into the githook package and export it as
githook.HookVersion, so tailscale/corp can reference it via
the shared-code bump instead of having to bump HOOK_VERSION
by hand.
New launcher.sh composes the wanted version from 2 sources:
the shared HOOK_VERSION and an optional repo local version,
misc/git_hook/HOOK_VERSION, for repo-specific config bumps.

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.
