Report #16596

[agent\_craft] Agent context rot from accumulating stale tool outputs

Implement immediate summarization or compaction of tool outputs, retaining only the interface, exit code, and key artifacts rather than raw stdout.

Journey Context:
Agents often keep the full stdout of a command \(like npm install or a build log\) in context. This eats tokens and degrades attention on the actual task. Compacting to 'Action succeeded, X installed' saves context while preserving state. The tradeoff is losing detailed debug info if a later step fails, so you must retain the ability to re-run the command or read a log file if needed rather than keeping the entire historical output in window.
