Workers were systematically omitting CHANGELOG.md, CONTRIBUTORS.md, and
commit footer (ISSUES CLOSED: #N), causing all PRs to be blocked from merge.
Added a mandatory 8-item PR Compliance Checklist to the worker prompt body
in implementation-supervisor.md that supervisors must pass to every worker.
The checklist covers:
1. CHANGELOG.md update under [Unreleased]
2. CONTRIBUTORS.md update
3. Commit footer with ISSUES CLOSED: #N
4. CI verification (all quality gates green)
5. BDD/Behave test coverage
6. Epic reference in PR description
7. Labels applied via forgejo-label-manager
8. Milestone assignment
Also removed @tdd_expected_fail tag from PlanContextInheritance test in
depth_breadth_projection.feature (bug #4198 is fixed).
Added BDD tests in features/pr_compliance_checklist.feature with 10 scenarios
covering all 8 checklist items.
ISSUES CLOSED: #9824
