[agent\_craft] Retrieved code chunks are irrelevant to the current edit

Augment the retrieval query with the current file path, recent edit history, and the active subgoal; retrieve with multiple strategies \(symbol search, semantic, exact identifier\); then re-rank by overlap with the changed region. Return at most 3-5 chunks plus their file paths.

Journey Context:
Naive RAG retrieves by question text, but coding context is positional and stateful. The current file, recent diffs, and the TODO list are stronger signals than the user's original request. LangChain's RAG patterns emphasize query construction and re-ranking, but for code the domain-specific twist is using AST symbols and edit distance. Without re-ranking, retrieval floods the context with neighbors instead of callers.
