Crawailer Developer 7634f9fc32 Initial commit: JavaScript API enhancement preparation
- Comprehensive test suite (700+ lines) for JS execution in high-level API
- Test coverage analysis and validation infrastructure
- Enhancement proposal and implementation strategy
- Mock HTTP server with realistic JavaScript scenarios
- Parallel implementation strategy using expert agents and git worktrees

Ready for test-driven implementation of JavaScript enhancements.
