- Extract _resolve_base_type and _validate_component as module-level helpers
- Replace ForwardRef._evaluate private API with eval in module namespace
- Remove broad except Exception in __init_subclass__, _component_base always set
- Replace direct _entries mutation in strategy.py with register() call form
- Remove dead TOKENIZER_CLASSES registry from AutoTokenizer
- Extract ModelFactory(BaseFactory[nn.Module]) as pure factory
- AutoModel now inherits only nn.Module, no factory state
- Move @AutoModel.register to @ModelFactory.register in transformer.py and encoder.py
- Add __getstate__/__setstate__ to drop cached _compiled Jinja2 template
- Jinja2 Template.root_render_func is a dynamic closure unpicklable by reference
- cached_property rebuilds the template lazily on first render after unpickle
- encode(str) single-thread, encode(List[str]) Rust parallel encode_batch
- apply_chat_template accepts single Messages or List[Messages] for batch
- add Message/Messages type aliases at module level
- ChatTemplate: defer Jinja2 compilation to cached_property, exclude compiled template from __getstate__ (its dynamic root function has __module__=None and falls back to __main__, breaking pickle)
- AutoTokenizer: bypass __getattr__ for underscore-prefixed attrs to prevent infinite recursion during unpickle when __dict__ is empty
