GitHub Actions 6c99372c52 fix(ci): add workflow orchestration for supply chain verification
Resolves issue where supply-chain-verify.yml ran before docker-build.yml
completed, causing verification to skip on PRs because Docker image
didn't exist yet.

**Root Cause:**
Both workflows triggered independently on PR events with no dependency,
running concurrently instead of sequentially.

**Solution:**
Add workflow_run trigger to supply-chain-verify that waits for
docker-build to complete successfully before running.

**Changes:**
- Remove pull_request trigger from supply-chain-verify.yml
- Add workflow_run trigger for "Docker Build, Publish & Test"
- Add job conditional checking workflow_run.conclusion == 'success'
- Update tag determination to handle workflow_run context
- Extract PR number from workflow_run metadata
- Update PR comment logic for workflow_run events
- Add debug logging for workflow_run context
- Document workflow_run depth limitation

**Behavior:**
- PRs: docker-build → supply-chain-verify (sequential)
- Push to main: docker-build → supply-chain-verify (sequential)
- Failed builds: verification skipped (correct behavior)
- Manual triggers: preserved via workflow_dispatch
- Scheduled runs: preserved for weekly scans

**Security:**
- Workflow security validated: LOW risk
- workflow_run runs in default branch context (prevents privilege escalation)
- No secret exposure in logs or comments
- Proper input sanitization for workflow metadata
- YAML validation passed
- Pre-commit hooks passed

**Testing:**
- YAML syntax validated
- All references verified correct
- Regression testing completed (no breaking changes)
- Debug instrumentation added for validation

**Documentation:**
- Implementation summary created
- QA report with security audit
- Plan archived for reference
- Testing guidelines provided
