Add /log and /debug commands for troubleshooting
- /log command to view and analyze automation logs - Filter by pattern, date, or log type - List available log files - /debug command generates comprehensive debug report - Version, core files, state, memory, scripts status - Environment info (Python, kubectl) - Disk usage by directory - JSON output mode for scripting - Updated shell completions with 13 aliases total - Test suite now covers 21 tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
