serversdown 84c4f75e03 feat: in-app live log (SSE activity feed)
Turn the inert "Show Work" thinking panel into a real live activity log:
- lyra/logbus.py: thread-safe in-memory ring buffer other modules publish to
- chat.respond logs backend/model/embed per turn, recall counts, reply size;
  web layer logs chat errors
- server: replace the keep-alive /stream/thinking stub with /stream/logs, an
  SSE endpoint that replays the recent buffer then streams new events
- UI: repurpose the panel as a global "Live Log" — connects on load, renders
  level/time/msg/fields, drops the old per-session localStorage + dead popup

Every turn now shows its backend + model in-app, so local-vs-cloud (free vs
paid) is visible at a glance.
