+ * Ensure session idle-reset is configured in ~/.openclaw/openclaw.json.

+ * By default OpenClaw resets the "main" session daily at 04:00 local time,
+ * which means conversations disappear after roughly one day.  ClawX sets
+ * `session.idleMinutes` to 10 080 (7 days) so that conversations are
+ * preserved for a week unless the user has explicitly configured their own
+ * value.  When `idleMinutes` is set without `session.reset` /
+ * `session.resetByType`, OpenClaw stays in idle-only mode (no daily reset).
