Replace the single docs/agents/action/debug.md with a debug/ directory
hosting three distinct workflows: local-deploy debugging, fully
automated CI pipeline triage via gh, and inspection of operator-placed
log files. Add full pipeline triage flow (enumerate failed runs and
children, classify branch-caused vs external, dedup-then-create issues
on s.infinito.nexus, iterate per role batches with APPS cap, push the
fix branch, file follow-up issues for unresolved root causes).
