feat: add plugin integration analysis to config-analyze command

Add automatic detection of active marketplace plugins and verification
that CLAUDE.md properly references them. This ensures projects using
marketplace plugins will have proper documentation to guide Claude Code
in using available tools.

Changes:
- Add claude-md-integration.md snippets to all 4 plugins (projman,
  cmdb-assistant, claude-config-maintainer, project-hygiene)
- Update marketplace.json with MCP server mappings for plugin detection
- Enhance /config-analyze to detect active plugins via MCP server names
- Update maintainer agent with plugin integration workflow
- Add plugin coverage percentage to analysis report
- User confirmation required before adding plugin references

+| `/sprint-start` | Begin sprint execution with relevant lessons learned |
+| `/sprint-status` | Check current sprint progress and identify blockers |
+| `/sprint-close` | Complete sprint and capture lessons learned to Gitea Wiki |
+| `/labels-sync` | Synchronize label taxonomy from Gitea |
+| `/initial-setup` | Run initial setup for projman plugin |
+
+### MCP Tools Available

+- Use `suggest_labels` when creating issues to ensure proper categorization
+- Search lessons learned with `search_lessons` before implementing features to avoid repeated mistakes
