Report #82432

[agent\_craft] Agent context window exhausts rapidly from raw tool outputs

Implement a rolling compaction pipeline that intercepts tool outputs \(like \`ls -R\` or \`cat\`\), summarizes or extracts diffs before appending to the message history, and never stores raw stdout directly in the context window.

Journey Context:
Agents naively appending full command outputs quickly hit token limits. Naive truncation cuts off the tail, which is often where the actual error message or final result lives. A compaction step \(e.g., extracting only \`\+/-\` lines from a diff, or summarizing a long log\) preserves the signal-to-noise ratio, extending the agent's operational lifespan without losing critical state.
