Module chunker 

Text chunking with multiple content-aware strategies.

Strategies:

• ChunkingStrategy::Plain: recursive splitting (original behavior, default)
• ChunkingStrategy::Sentence: sentence-boundary-aware splitting with overlap
• ChunkingStrategy::Code: code-aware splitting that avoids breaking function bodies
• ChunkingStrategy::Markdown: markdown-header-based splitting on header boundaries

Functions

chunk_text

Chunk text using the configured strategy and token counter.
