feat: add analytics tracking to key components

- Track tab creation and closure events in TabManager
- Add session tracking (created, resumed, completed) in ClaudeCodeSession
- Track model selection changes in ClaudeCodeSession
- Monitor agent execution events (success/failure) in AgentExecution
- Include execution duration metrics for agents
- Use useTrackEvent hook for consistent event tracking
