[agent\_craft] Context rot from accumulating raw tool outputs

Summarize or extract structured data from tool outputs immediately after execution. Discard raw stdout from the active context window and persist it to external memory if needed for later retrieval.

Journey Context:
Agents often keep the full stdout of commands like \`ls -R\` or \`cat file\` in context. This fills the window with low-density tokens, pushing out the system prompt or early instructions. Naive truncation by the API will drop the system prompt first. Compaction loses some detail but preserves working capacity for reasoning. RAG for old outputs is too slow for active task steps, making in-window summarization the optimal tradeoff.
