🎯 refactor: implement comprehensive BDD test suite with modular architecture

✨ feat: add feature-based test organization per ADR 0024
🐛 fix: resolve compilation errors in suite_feature.go
📝 docs: add comprehensive BDD framework documentation
♻️ refactor: split monolithic tests into modular features
🧪 test: implement synchronization helpers and context management
⚡ perf: add parallel test execution capability
🔧 chore: add feature-specific test scripts and validation
📚 docs: move BDD_TAGS.md to features/ for better organization
