chore(release): v1.34.21 — macOS updater UI fix + second test build

- AppUpdater.tsx: macOS now has a dedicated branch in the update modal —
  no architecture-specific DMG asset shown (the Tauri Updater picks the
  right platform from latest.json), clearer wording ("Downloads, verifies
  and installs automatically"), and the primary button reads "Install
  now" instead of "Download". Strings use defaultValue so locales without
  the key fall back to English until translations catch up.
- Test release for the updater pipeline; CHANGELOG entry asks users to
  ignore it. Will be deleted after the test.

 > **🎉 macOS users:** Starting with **v1.34.15**, Psysonic can **update itself silently**. No more DMG downloading and dragging to Applications — the updater fetches the signed `.app` bundle, verifies the signature, replaces the app in place, and relaunches. Just click "Update" when the toast appears.

+> **This is a throwaway test build used to verify the macOS auto-updater pipeline end-to-end. There are no new features, no bug fixes, no changes of any kind that affect how Psysonic behaves for end users — only the version number, plus a small UI polish in the update notification on macOS.**
+>
+> **This release will be deleted within a day or two.** Do not download it, do not rely on it, do not link to it. Stay on whatever version you currently have installed; normal releases will resume shortly under the regular versioning scheme.
+>
+> Thanks for your patience while we stabilise the updater infrastructure.
