Fixed in v1.27.5.

Root cause: net::ERR_NETWORK_IO_SUSPENDED is Chromium's error when the machine sleeps mid update-check — benign and unactionable, exactly the class isTransientNetworkError() already filters out of Sentry (cf. #15 ERR_INTERNET_DISCONNECTED). It simply wasn't in the regex.

Added NETWORK_IO_SUSPENDED to the filter in src/main/autoUpdater.ts, so it now surfaces as a benign "no update available" state and stays out of Sentry. Regression test added to tests/electron/autoUpdater.test.ts (20 pass). Genuine errors (e.g. sha512 mismatch) still report.
