refactor(lock): restructure lock crate, remove unused modules and clarify directory layout

- Remove unused core/rwlock.rs and manager/ modules (ManagerFactory, LifecycleManager, NamespaceManager)
- Move all lock-related code into crates/lock/src with clear submodules: client, core, utils, etc.
- Ensure only necessary files and APIs are exposed, improve maintainability
- No functional logic change, pure structure and cleanup refactor
