chore: remove deprecated templates and unused files

- Delete archived layer-based templates (Layer 1-4)
- Remove hierarchy-analysis.txt (no longer needed)
- Update intelligent-tools-strategy.md to remove references

Cleanup:
- Keep only claude-module-unified.txt in memory/ directory
- Remove outdated template references from strategy document
- Simplify template structure for installation
