Add timeout handling, execution tracking, and job summary

Enhance the Run CAgent step with:

Timeout Support:
- Implement timeout using bash 'timeout' command
- Exit code 124 indicates timeout occurred
- Clear error message when timeout is reached

Execution Time Tracking:
- Track start and end time of agent execution
- Output execution-time in seconds for use in subsequent steps

GitHub Actions Job Summary:
- Create formatted markdown summary table
- Show agent name, exit code, execution time, versions
- Visual status indicators (✅ success, ❌ failed, ⏱️ timeout)
- Expandable section with last 100 lines of agent output
- Summary appears in GitHub Actions UI for easy review

Debug Mode Support:
- Enable bash tracing (set -x) when debug mode is on
- Output working directory and workspace paths
- Log exit code, execution time, and output file location
