ConfigurO 3.1

Fixes

• A quarter of the app catalogue was still served links by the archived
  project this was forked from. 38 of the 147 entries had no link of their own
  and silently fell back to that feed, which was frozen in January 2026 with
  links pinned to 2021 builds — Opera 81, Blender 2.93, OBS 27, Rufus 3.18,
  32-bit Node 16. Two had rotted: Epic's installer 404s, and VLC's .exe URL
  answers 200 with an HTML page, which the app would have saved under the .exe
  name in the URL and then run. All 38 are now resolved here, and every emitted
  link is verified to serve a real Windows installer.

Housekeeping

• The feed generator no longer contacts the upstream repository at all, and the
  Tag field it existed to copy — which nothing ever read — is gone.
• The single-instance guard is named after this app rather than the one it was
  forked from. Two versions may briefly run at once across this one upgrade.
• Attribution is unchanged and stays where it belongs, in
  THIRD-PARTY-NOTICES.md and the README.
