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 Signed-off-by: dandan <dandan@dandandeMac-Studio.local>
