- Remove bashcov from CI bats job (crashed on read-only fs, masked BATS_EXIT)
- Remove stale bats-cov volume (no longer needed)
- Add shell: bash to commit-status steps (sh doesn't support ${VAR:0:8})
- set +e first in bats step to catch all errors (docker pull, apk, etc.)
- Tool error → BATS_EXIT != 0 → commit-status failure → PR merge blocked
