feat(cli): add 'bunx oh-my-opencode run' command for persistent agent sessions (#228)

- Add new 'run' command using @opencode-ai/sdk to manage agent sessions
- Implement recursive descendant session checking (waits for ALL nested child sessions)
- Add completion conditions: all todos done + all descendant sessions idle
- Add SSE event processing for session state tracking
- Fix todo-continuation-enforcer to clean up session tracking
- Comprehensive test coverage with memory-safe test patterns

Unlike 'opencode run', this command ensures the agent completes all tasks
by recursively waiting for nested background agent sessions before exiting.
