Pattern-matches known-recoverable MCP tool failures and injects a
synthetic imperative message into the conversation right after the
failing tool result. Static prompt rules lose to accumulated tool
reality (we've shipped 4 orphan twenty-* services because the model
ignored the "no delete-and-recreate" rule); a fresh role:'user'
message at decision time does not.
Initial rules cover the three highest-confidence Docker failure
patterns: orphan container conflict (use apps_unstick), image pull
denied (use apps_repair), port already allocated (identify holder).
Each rule names the wrong-but-tempting move explicitly.
See AI_HARNESS_GAPS.md §1 for the failure case this addresses.
