refact(docs): compose-era sweeps retire with the last compose file

rank 7 tail. dankserver/compose.yaml (a parallel inventory whose mounts
had diverged from the quadlets) and its .env.example live in
dankserver/.AGENTTRASH/20261013-compose-retire/; the retired ik chat
template joined scripts/.AGENTTRASH/. No target has a compose file now:
- service-map drops the compose selection rule, compose file claim, and
  check_compose (the check list is schema/units/ownership/config/drift);
- deploy-remote's compose fallback is a loud failure, not a WARN-and-
  nothing for dankserver;
- compose_validity.bats goes to tests/.AGENTTRASH (it was sweeping only
  the trash file); env_consistency sheds its two compose sweeps;
- docs_completeness's compose sweep skips .AGENTTRASH so retired
  services cannot resurrect, and a revived compose stays covered;
- Testing Policy drops the Compose validity row.
