Add WebView2 additional_browser_args to disable Chromium background throttling
(--disable-background-timer-throttling / -renderer-backgrounding /
-backgrounding-occluded-windows) so the existing JS Matrix /sync loop and
notifications keep running full-speed when the app is closed to the tray, instead
of standing up a second headless Rust sync client. Tauri's default WebView2 args
are preserved (setting this overrides them). Windows/WebView2 only; does not block
system sleep (that's P5-46, calls-only). CI Windows compile pending.
