Remove event logging from session files - only save messages and state changes

Browse Source 
Session reconstruction only needs:
- type: 'session' - session metadata
- type: 'message' - conversation history
- type: 'thinking_level_change' - thinking level changes
- type: 'model_change' - model changes

Events like agent_start/end, tool_execution_start/end are not needed for
session reconstruction and only added bloat. This reduces session file size
significantly and speeds up writes.
