v0.1.20

• Defer active-goal continuations queued by session_compact until the compaction event has unwound, avoiding nested prompt/auto-compaction races in Pi’s compaction lifecycle.
• Accelerate pending idle continuation retries after compaction so length-stop recovery resumes promptly once the host is idle.
• Ignore stale compact usage snapshots during reconstruction so old runtime entries cannot rewind usage, reactivate completed goals, or downgrade budget-limited goals.
• Expand regression coverage for reported long-session failures: host retry cancellation, duplicate session_compact coalescing, shutdown cancellation, host overflow suppression, and stale runtime usage entries.
