Generate per-architecture .appinstaller feeds served from the stable releases/latest/download URL, embed them as Update.appinstaller with uap13:AutoUpdate, validate them in Test-Packages.ps1, and enable them for release builds. Inspired by dotMorten/GitHubToDo. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Adopts the approach from dotMorten/GitHubToDo: publish an App Installer feed at GitHub's stable
releases/latest/download/URL so installed MSIX packages update themselves from new GitHub Releases.Changes
New-AppInstaller.ps1(new): generates a per-architecture feed (Devolutions.Terminal_<arch>.appinstaller). The feed URI isreleases/latest/download/...;MainPackagepoints to the immutable MSIX for the release tag. Checks run on launch (non-blocking, no prompt) and through the background task.Build-Packages.ps1: new-UpdateRepository/-ReleaseTagparameters. When set, it writes the feeds next to the MSIX files, embeds each feed asUpdate.appinstaller, and adds auap13:AutoUpdatereference.uap13is ignorable, so older Windows versions skip it.Test-Packages.ps1:-UpdateRepositoryvalidates that the embedded feed matches the package's identity, architecture, file name, and stable URI, and that it is hash-identical to the published feed. Without the parameter, it asserts that no feed is embedded.Test-PackageBuild.ps1: adds an AutoUpdate case plus negative tests (missing feed, wrong repo, unexpected feed, divergent published feed, missing tag).UpdateRepository=$GITHUB_REPOSITORY. The feeds flow into the existing release assets.docs/release.md"MSIX automatic updates", package README.Per-architecture feeds are used because this repo ships separate x64/arm64 MSIX files, not a bundle.
Testing
Test-PackageBuild.ps1passes locally, including the new AutoUpdate and failure cases. makeappx accepts the uap13 manifest.Follow-up (not included)
Package.CheckUpdateAvailabilityAsync), as GitHubToDo does.
