stitchkit v0.112.1

Fixed

• stitchkit/agent-runtime — an empty or control-only failed assistant now retains its non-success marker when explicitly included with evidencePolicy.failedAssistant: 'assistant-marked'. The default still omits failed evidence. The compaction guide explains the existing failed-prefix recovery policy, status-aware summarization, and why a closed tool exchange cannot settle an external effect. → ADR 0269
