feat: add Docker tag monitoring and comprehensive documentation
- Add docker-tag-monitor.yml workflow for automatic monitoring: - Hourly checks for missing Docker images - Auto-triggers CI/CD for missing tags - Creates GitHub issues for tracking - Provides comprehensive status reporting - Update CLAUDE.md with detailed Docker tag strategy documentation: - Document all tag types (latest, stable, version, branch, testing) - Explain automated workflows and their interactions - Provide usage examples and best practices - Document monitoring and cleanup features This completes the Docker tagging system overhaul with: ✅ PAT-based auto-tagging for workflow triggering ✅ Improved Docker tagging strategy with clear separation ✅ Automated monitoring and issue creation ✅ Comprehensive documentation for future maintenance

The following Git tags do not have corresponding Docker images on Docker Hub:
116+
117+
${missingTags.map(tag => `- \`${tag}\``).join('\n')}
118+
119+
### Possible Causes:
120+
1. **Workflow Trigger Issue**: The CI/CD workflow was not triggered when these tags were created
121+
2. **Build Failure**: The Docker build failed for these tags
122+
3. **Token Permissions**: The auto-tag workflow lacks permissions to trigger CI/CD
123+
124+
### Recommended Actions:
125+
1. Check the CI/CD workflow runs for these tags
126+
2. Manually trigger the CI/CD workflow if needed:
127+
\`\`\`bash
128+
gh workflow run ci-cd.yml --ref TAG_NAME -f reason="Manual trigger for missing Docker image"
129+
\`\`\`
130+
3. Verify that PAT_TOKEN secret has proper permissions
131+
132+
### Auto-Resolution:
133+
This monitor has already attempted to trigger CI/CD workflows for the missing tags.
