Subject: [PATCH] Add auto-release workflow on dev-to-main merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Automatically creates a GitHub release when dev is merged to main,
reading the version from the App csproj. The existing build workflow
then triggers and attaches per-platform zips.

Flow: bump version on dev → merge dev to main → release + zips auto-created
