feat: re-enable typos hook in CI with fresh cache invalidation

Phase 4: Typos Hook Re-activation
- Re-enabled typos hook in CI workflow after cache invalidation
- Removed SKIP=typos environment variable
- Enhanced typos.toml configuration should handle all spelling issues
- Fresh cache keys ensure no legacy tool conflicts

Cache Invalidation Strategy Applied:
✅ Updated terraform-tools cache key to v2-cache-invalidation
✅ Updated pre-commit hooks cache key to v2-cache-invalidation
✅ Added explicit pre-commit clean step
✅ Enhanced logging for debugging

Local Development:
✅ Comprehensive typos.toml with 15+ misspelling patterns
✅ Enhanced pre-commit hook configuration
✅ Complete spell-check documentation in .github/SPELL_CHECK.md

This should resolve the persistent typo errors in CI while maintaining
robust spell-checking for both local development and CI environments.
