domainTokenizer — Building small models that understand domain tokens, not just words.

Core components:
  - schema: DomainSchema, FieldSpec, FieldType
  - tokenizers: DomainTokenizerBuilder, per-field tokenizers
  - schemas: Predefined schemas (FINANCE, ECOMMERCE, HEALTHCARE)
  - models: DomainTransformerForCausalLM, PLR, JointFusion
  - training: prepare_clm_dataset, pretrain_domain_model
