chore: superclean compliance pass

- Migrate .wiki/ to .github/wiki/ (GCI standard for public repos)
- Add _Sidebar.md for GitHub Wiki navigation
- Update wiki-sync.yml to reference .github/wiki/ path
- Remove .markdownlintignore (covered by .vscode/settings.json)
- Migrate .allow-ai-terms to ALLOW_AI_TERMS_REPOS in pre-commit hook
- Expand .gitignore with full IDE and AI agent directory list
- Update README project structure reference
