Release workflow now names the installer asset ClaudeDo.Installer.exe (no version) for a permanent download URL; it is still uploaded and checksummed on every release. App + worker keep the git tag version.
Removes the self-update preflight from App.OnStartup and deletes the now-dead SelfUpdater / SelfUpdatePromptWindow / SelfUpdateResult plus their tests. App-update detection is unaffected: the manifest records the release tag via DownloadAndExtractStep.
Updates the installer CLAUDE.md.
