Report #8080

[agent\_craft] Semantic retriever returns tangentially related but functionally useless code chunks like docstrings instead of implementations

Use a two-stage retrieval: fast semantic search to find candidate files, followed by a structural/AST retrieval to extract the exact function definitions or class signatures into context.

Journey Context:
Pure vector similarity struggles with code because 'usage' and 'definition' are semantically similar but functionally distinct. A comment saying 'handles auth' matches the query 'how is auth handled' better than the actual \`def check\_token\(token\):\` function. Code requires structural awareness, not just semantic similarity, to provide actionable context.
