* Manus Debug Collector (agent-friendly)
*
* Captures:
* 1) Console logs
* 2) Network requests (fetch + XHR)
* 3) User interactions (semantic uiEvents: click/type/submit/nav/scroll/etc.)
*
* Data is periodically sent to /__manus__/logs
* Note: uiEvents are mirrored to sessionEvents for sessionReplay.log
