- Added ripgrep (rg) usage notes and preference over grep for targeted searches
- Updated log discovery examples to use rg with --fixed-strings for workflow/job name searches
- Added failure-marker search pattern (❌|Traceback|FAILED|etc.) for quick issue identification
- Replaced grep with rg in runner health checks (dmesg, journalctl)
- Added failure marker search to quick-start one-liner
- Preserved awk usage for tab
Added comprehensive documentation for autonomous investigation of failed Gitea Actions runs via SSH access to gitea-runner host. Includes log location mapping, classification heuristics for distinguishing workflow/dependency/application/service/infrastructure failures, and evidence-based debug suggestion templates. Provides read-only investigation sequences with safety constraints to prevent conflating application failures with runner inst
