feat(desktop): show real version in top-bar badge

Vite `define` injects __APP_VERSION__ from apps/desktop/package.json
into both main and renderer at build time; the Wordmark badge now
renders 'v0.1.2' instead of the static 'pre-alpha' / '预览版' i18n
string. The i18n key stays in place for anyone who still references
it from elsewhere.

Also re-pins productName to 'Open CoDesign' (artifact filenames remain
pinned to the open-codesign slug) and updates the macOS install hint
path to /Applications/Open CoDesign.app with a parenthetical for the
legacy 0.1.x bundle path.
