refactor(hooks): drop @socketsecurity/ scope from internal hook packages

Internal-only hook packages (path-guard, token-guard, check-new-deps,
setup-security-tools, public-surface-reminder) are private:true and
never published to npm — the @socketsecurity/ scope was misleading.
Renamed to bare hook-<name> across package.json, README.md, and test
file references.
