v0.3.7

Added

• Internal benchmarking infrastructure for dataclasses and pydantic models (Makefile, pytest marks), benchmark tests

Changed

• lru_cache for resolve() and parse() operations to improve pipeline speed
• Pre-calculated field indexes in ResolvedModel (field_map, constrained_paths, etc.) to remove multiple DFS traversals during planning and resolving
• Optimized generate_invalid logic by splitting loops, removing tuple allocations, and simplifying recursion
• ResolvedField refactor to store FieldSpec directly instead of copying values
