This change updates the release workflow to use display-only titles that match the release mode: run shows the base version (for example 1.2.1), while beta shows BETA {base}. The real tag/version remains unchanged for updater compatibility. The release notes plan document was also updated to document this naming convention.
This commit hardens the release workflow against transient Electron binary download failures by switching Electron and electron-builder downloads to the npmmirror mirror and adding a single retry around the SignPath packaging step. This addresses intermittent TLS disconnects during CI builds without changing the release process itself.
Enable prerelease updates and make release discovery more robust. Set autoUpdater.allowPrerelease = true to ensure {base}-{buildId} prerelease tags are detected. Add compareVersionTags to compare X.Y.Z-buildId where buildId is compared numerically. discoverLatestTag now collects candidates from both /releases/latest HTML and the (proxied) GitHub API, picks the newest by the comparator, and logs candidates. Also continue trying other mirrors when a mirror reports no update. Update docs and CI workflow comments to explain the prerelease behavior.
