Juan Denis 3ff432be25 Add activity event store and UI ...

Introduce a small append-only events store and surface agent lifecycle/activity events to the UI. Adds internal/events with a concurrent ring buffer (capacity 200) and optional JSON persistence (events.json next to agent data), plus Append/Snapshot/Clear APIs. Wire the store into Agent (create store, GetEvents, append service start/stop/restart and connection transition events) and add connectionWatcher to emit WS connect/disconnect events.

Expose events via IPC (/events) and update the IPC client and hooks (ipc.events, useEvents) so the frontend can poll for new events. Implement a complete Activity page UI (list, icons, severity filter) and corresponding styles. Persistence is best-effort and safe (temp-file rename); malformed or missing files are ignored to avoid startup failures.
