[agent\_craft] RAG pipeline injecting irrelevant context that degrades agent reasoning

Implement a two-stage retrieval pipeline: a broad retriever \(e.g., vector search\) followed by a lightweight relevance classifier \(or the LLM itself via a forced-evaluation step\) that filters chunks before injecting them into the main agent context.

Journey Context:
Naive RAG pipelines retrieve top-K chunks and dump them into the prompt. If K is too high, the agent suffers from 'lost in the middle' and wastes context window on irrelevant text, leading to worse generations than no context at all. The tradeoff is added latency/compute for the filtering step vs. context pollution. Filtering is the right call because context window space is the most expensive resource in an agent loop.
