+# - If openclaw.pid exists and process is alive => running unless logs are stale.
+# - If process alive but log file hasn't changed for STALL_AFTER_SECONDS => stalled.
+# - Otherwise => idle.
+#
+# Future extension point:
+# - Replace/augment log-freshness with real main-agent session/ledger signals.
