feat(strategies): implement all 5 chunking strategies
Why:
- Core evaluation targets — each strategy chunks differently for comparison
Changes:
- fixed_size: token-based splitting with overlap (baseline)
- recursive: cascade splitting (headers → newlines → sentences → words)
- semantic: sentence-level embeddings with similarity-based boundaries
- contextual_retrieval: LLM-generated context prefixes per chunk (Anthropic research)
- semantic_parent_child: paragraph clustering into parent-child hierarchy
