v3.25.7

Fixed

• OpenClaw session sidebar no longer stalls the whole portal: the main Agent Chat sessions list now uses session metadata instead of opening large transcript/checkpoint files just to build sidebar labels and previews, which stops event-loop stalls that were making gateway chat, hosted pages, and shared pages look like they were disconnecting or timing out.
• Main-session list polling is bounded instead of re-parsing the world on every refresh: the parsed OpenClaw main-session registry is now cached briefly by file stat, which keeps admin/session polling from pinning the Node main thread on busy installs.
