feat(ci): add timeout parameter to add-debug-wait command

Add optional timeout parameter (1h-72h) to customize wait duration
in CI debugging jobs. Defaults to 3h when omitted.

Implementation includes:
- Fixed Python section boundary detection for test: section
- Timeout normalized to Go duration format (e.g., "8h" → "8h0m0s")
- Added best_effort: true when timeout is customized
