fix: handle compound commands in terminal integration

- Add compound command detection to track multi-process commands
- Implement process completion tracking for operators like &&, ||, ;, |
- Wait for all processes in compound commands before reporting to LLM
- Add comprehensive tests for compound command scenarios

Fixes #7430
