Report #13756

[agent\_craft] Agent retrieves code snippets via RAG that are syntactically incomplete, causing it to hallucinate the rest of the code

Use AST-aware chunking for code retrieval instead of fixed-size text chunking. Ensure chunks always include complete function/class definitions and necessary imports.

Journey Context:
Standard text splitters \(e.g., 512 tokens with overlap\) destroy code structure. An LLM receiving half a function will invent the missing half, often incorrectly. AST parsing ensures chunks are semantically complete. If a chunk is too large, summarize the docstring but keep the signature and core logic intact.
