Module State 

State Module (ExtensionState)

RESPONSIBILITIES

Combines all extension-related state components into a single state struct.

ARCHITECTURAL ROLE

State is the main composite struct that combines all ExtensionState components:

• ExtensionRegistry: Command registry and provider handle management
• ProviderRegistration: Language providers registration
• ScannedExtensions: Discovered extensions metadata

KEY COMPONENTS

• State: Main struct combining all extension state
• Default: Initialization implementation

ERROR HANDLING

• Thread-safe access via Arc<Mutex<...>>
• Proper lock error handling with MapLockError helpers

LOGGING

State changes are logged at appropriate levels (debug, info, warn, error).

PERFORMANCE CONSIDERATIONS

• Lock mutexes briefly and release immediately
• Avoid nested locks to prevent deadlocks
• Use Arc for shared ownership across threads

TODO

• Add extension state validation invariants
• Implement extension lifecycle events
• Add extension state metrics collection
