test: add 58 new upstream merge guard tests

- Sync `merge-config.json` with `config.ts` (22 → 39 skipFiles patterns)
- Add skipFiles tests for all newly skipped upstream configs (glossary,
  triage tools, AGENTS.md, storybook workflow, etc.)
- Add forbidden file/dir existence checks for all skipped items
- Add repository hygiene tests: `__pycache__` in .gitignore,
  altimate-engine existence, bridge directory
- Add config consistency tests: merge-config.json ↔ config.ts sync

Total: 170 → 228 tests (58 new)
