Pass the installed version with the startup language so the renderer can display it before asynchronous initialization.
Seed and start the upload sparkline immediately, keep a fixed update-action slot across all update states, and remove the delayed automatic update check.
Add first-frame regression coverage for version, speed baseline, update geometry, and startup query behavior.
Move upload activity out of the global footer into a compact eight-row sidebar panel, add vertical metric transitions, and draw a smoothed green upload-speed sparkline in the header. Localize the new surfaces, cover responsive Electron behavior, and extend the strict public source allowlist for the new bounded speed-history module and its tests.
