Companion to the same addition in the cloud-init and ansible repos.
Caught real drift in those repos in a recent session only because
the user explicitly asked. Codify the sweep with concrete, repo-
specific drift hotspots rather than a vague 'watch for drift' rule
that gets ignored.
Each AGENTS.md addition lists the doc files most likely to fall
behind code changes here, plus a quick-triage one-liner using
'git diff --name-only HEAD | xargs grep -l ...' so the rule is
actionable not aspirational.
pi coding-agent container built on opencode-devbox:base-latest.
Includes Dockerfile, docker-compose, CI workflow, smoke-test,
README, CHANGELOG, AGENTS.md.
