[agent\_craft] RAG pipeline injects irrelevant code snippets diluting agent reasoning

Implement a two-stage retrieval pipeline: broad vector search followed by a cross-encoder reranker or LLM-based relevance filter before injecting chunks into the main agent context.

Journey Context:
Naive RAG stuffs top-K chunks into the prompt. For code, top-K often pulls in deprecated functions or unrelated implementations that share variable names. This forces the agent to waste attention on irrelevant code, causing hallucinations or 'lost in the middle' effects. Filtering before injection costs an extra API call or compute step, but saves the primary context window for high-signal data, drastically improving code generation accuracy.
