docs: enhance JSDoc for DockerOrchestrator cleanup methods

- Add detailed documentation for `cleanup()` and `cleanupFailedStart()` methods
- Clarify the purpose, behavior, and differences between the methods
- Document parameters, return values, and error handling
- Add @remarks sections for important implementation details
