KeyFlow v2.1.1

[2.1.1] - 2026-05-28

Build and CI maintenance release — no changes to remapping behavior.

Added

• CI now builds a Release binary on every push to main and uploads it as a
  workflow artifact, so a tested build is always available without cutting a tag.

Changed

• keyflow.exe now embeds a Windows VERSIONINFO resource, so the publisher,
  version, and product name appear in the file's Properties → Details dialog.
