feat(web-ui): add pinned sessions and live monitor in Chat (#118)
* feat: add single-page live session monitor and chat pinning * fix: restore full test green after main merge * fix: use Array.from instead of Set spread for ts-node compatibility [...new Set()] requires downlevelIteration which isn't enabled in ts-node dev mode, causing sonic-boom crash on startup.
