feat: Enable sparse checkout and add comprehensive validation layers

- Enable USE_GIT_SPARSE_CHECKOUT for 10-20x performance improvement
- Add Layer 2: CDK native validation using ManifestDeclarativeSource
- Add Layer 3: SPEC execution test for each manifest connector
- Add comprehensive logging for all validation failures
- Implement three-layer validation: JSON schema + CDK validation + SPEC execution
- Performance optimization: git sparse-checkout vs HTTP downloads
- Enhanced error tracking with separate failure categories
