Fix update DMG installation flow

[GordonBeeming]

Summary

• package Insomnia.app beside an /Applications shortcut in release DMGs
• name the updater action after its actual download-and-open behavior

Why

The in-app download opened a bare disk image containing only Insomnia.app, leaving users without a clear installation path.

User impact

Downloaded updates now open as a conventional macOS installer where the app can be dragged to Applications.

Validation

• actionlint .github/workflows/build.yml
• swift build -Xswiftc -strict-concurrency=complete
• swift test (133 tests)
• created and mounted a local DMG; verified Insomnia.app and the /Applications shortcut

Summary by CodeRabbit

• New Features
  • Updated the update flow so downloaded installer media opens automatically to streamline installation.
• Bug Fixes
  • Improved disk image creation to ensure the installer is packaged correctly, including an Applications shortcut.
• Updates
  • Refined the update download action naming/labeling to better reflect that the installer is downloaded and then opened.

📝 Walkthrough

Walkthrough

The update menu action now calls a renamed method that downloads and opens the installer. The macOS release workflow creates the DMG from a temporary staging directory containing the app and an Applications symlink.

Code Review

This pull request renames the downloadAndInstall() method to downloadAndOpenInstaller() in UpdateChecker.swift and updates its call site in MenuBarView.swift. The reviewer noted that downloadAndOpenInstaller() is asynchronous but lacks @MainActor isolation, which can lead to UI state updates and AppKit calls running on a background thread. It is recommended to mark this method with @MainActor to prevent potential runtime issues or SwiftUI warnings.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
