YeonGyu-Kim f3ff32fd18 fix(background-agent): detect stale tasks that never received progress updates
Tasks with no progress.lastUpdate were silently skipped in
checkAndInterruptStaleTasks, causing them to hang forever when the model
hangs before its first tool call. Now falls back to checking startedAt
against a configurable messageStalenessTimeoutMs (default: 10 minutes).
