 * Manifest-backed init subcommand router.

 *
 * Phase 6: all init.* subcommands have SDK equivalents and are dispatched
 * via executeForCjs (the sync bridge). CJS fallback retained when:
 * - GSD_WORKSTREAM is active (workstream-scoped requests fall through to CJS).
 * - SDK is unavailable (build not present).
 *
 * CJS-only subcommands: none.
 * SDK-only (unsupported in CJS router): none.
