Major changes: - Replace monolithic SessionEvent with reason discriminator with individual event types: session_start, session_before_switch, session_switch, session_before_new, session_new, session_before_branch, session_branch, session_before_compact, session_compact, session_shutdown - Each event has dedicated result type (SessionBeforeSwitchResult, etc.) - HookHandler type now allows bare return statements (void in return type) - HookAPI.on() has proper overloads for each event with correct typing Additional fixes: - AgentSession now always subscribes to agent in constructor (was only subscribing when external subscribe() called, breaking internal handlers) - Standardize on undefined over null throughout codebase - HookUIContext methods return undefined instead of null - SessionManager methods return undefined instead of null - Simplify hook exports to 'export type * from types.js' - Add detailed JSDoc for skipConversationRestore vs cancel - Fix createBranchedSession to rebuild index in persist mode - newSession() now returns the session file path Updated all example hooks, tests, and emission sites to use new event types.
