Add comprehensive target configuration parsing and inheritance system: - Create internal/targets package with config structures - Support JSON configuration loading with inheritance resolution - Implement multi-level inheritance (e.g., rp2040 → cortex-m0plus → cortex-m) - Add 206 target configurations from TinyGo for embedded platforms - Support core fields: name, llvm-target, cpu, features, build-tags, goos, goarch, cflags, ldflags - Provide high-level resolver interface for target lookup - Include comprehensive unit tests with 100% target parsing coverage This foundation enables future -target parameter support for cross-compilation to diverse embedded platforms beyond current GOOS/GOARCH limitations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
