[frontier] Static vector RAG returns stale code context for rapidly evolving monorepos causing hallucinated imports

Adopt Just-in-Time Knowledge Compilation: instead of pre-indexed embeddings, parse live ASTs and OpenAPI specs on-query into ephemeral in-memory SQLite graph databases, run recursive CTE queries for precise multi-hop dependencies, and discard after session.

Journey Context:
Pre-computed embeddings lag behind git commits; agents reference deleted functions. The Aider tool pioneered 'repo maps'—on-the-fly compilation of code structure into queryable graphs. This trades indexing latency for accuracy, using SQL graph traversals \(parent-child imports\) rather than vector similarity, eliminating stale context drift entirely.
