debont80 7134a3d634 Harden app updater: per-hop redirect pinning, truncation + path-guard fixes
Review follow-ups on the in-app updater:

- Download via Electron net.request with redirect:'manual', re-validating the
  host on EVERY hop. fetch() followed redirects automatically and undici hides
  the Location header, so the trusted-host pin only covered the first URL — a
  302 from the trusted host could bounce the download to an arbitrary server.
- Reject truncated downloads (received !== Content-Length) and an 'aborted'
  mid-stream so a partial installer is never launched; clean up the temp file
  on any failure.
- runAppUpdate: compare the parent dir by equality instead of startsWith(),
  which a sibling like `<temp>_evil\x.exe` defeated.
- checkForAppUpdate: 15s AbortController timeout (mirrors the yt-dlp calls) and
  pin htmlUrl to the trusted host before handing it to the OS browser.
- parseVersion: ignore -prerelease/+build suffixes so a prerelease never sorts
  above its final release.
- SettingsView: funnel a failed check into the single error slot so two error
  messages can't render at once.
