Session Hooks Infrastructure

What: New architecture for temporary, session-scoped hooks that automatically clean up when sessions end How it works:

• Session hooks are stored separately from user settings (sessionHooks field in app state at line 141240)
• Automatically cleared on session end to prevent accumulation
• Support callback functions (onMatch) for programmatic responses
• Cannot be removed through settings UI (protected at diff lines 2057-2059)

Details:

• Three new management functions:
• wB1() at line 457341 - Retrieves session hooks for a specific session
• ll2() at line 457356 - Finds and returns matching hook callbacks
• il2() at line 457367 - Clears all hooks for a session
• Session hooks are merged with permanent hooks at execution time (merge logic in nl2() at line 457391)
• Hooks are marked with source: "sessionHook" to distinguish from settings-based hooks
• Designed for plugins, agents, and temporary automation without polluting user settings
• Evidence: State initialization at line 141240, management functions at lines 457341-457367, integration in nl2() at lines 457391-457413
