Retrigger CI to resolve transient docker build failure.
All code quality gates (lint, typecheck, unit_tests, integration_tests,
coverage) pass. The docker failure is a CI infrastructure issue unrelated
to this documentation-only PR.
Add Ten Merge Criteria section to pr-merge-pool-supervisor.md documenting
all 10 criteria the supervisor checks at runtime. Previously only 6 criteria
were documented, creating inconsistency with actual runtime behaviour.
Also update CHANGELOG.md and CONTRIBUTORS.md.
