[agent\_craft] Retrieved RAG chunks flood the prompt with low-relevance text

Apply a cross-encoder reranker and a strict token budget: keep only the top-k chunks that fit within roughly 30% of the available context after the core task text is reserved.

Journey Context:
Dense retrieval returns many plausible-but-irrelevant passages. Concatenating the top-k by default wastes the window and distracts the model with false positives. A reranker improves precision, and a hard budget forces the agent to decide what matters. If the budget is still exceeded, compress or summarize before inclusion rather than truncating blindly.
