Report #45308

[agent\_craft] Agent retrieves entire dependency libraries into context instead of just the required API signature

Implement a two-step retrieval: first, an indexer/searcher finds the file/class; second, an AST parser extracts only the public signatures and docstrings. Only retrieve the full implementation if the agent explicitly requests it.

Journey Context:
Naive RAG pipelines embed documentation chunks and return the top K. For code, this often returns the internals of a function, which is useless if the agent just needs to know the function signature to call it. Loading full implementations of dependencies quickly exhausts the context window. By defaulting to signature-only retrieval, the agent gets the API surface it needs to write code, keeping the context lean. It only pays the token cost for implementation details when debugging or modifying that specific dependency.
