Fix Story 1.3: StateStore spec compliance and minor cleanup

Critical Fix:
- StateStore now uses global Hooks.callAll directly (per spec)
- Removed hooks parameter from StateStore constructor
- Updated module.js to pass only adapter.settings
- Updated tests to stub globalThis.Hooks

Minor Cleanup:
- Fixed misleading warning in SocketHandler.registerPendingOp
- Added clarifying comment for setMatrix _revision behavior
