v4.3.2

Version-number fix — the v4.3.0 and v4.3.1 releases shipped code fixes
but forgot to bump the version strings in the desktop app, engine, and
payload. This release aligns all version numbers across every component.

• Fixed: all version strings now report 4.3.2 — package.json,
  tauri.conf.json, both Cargo.tomls, VERSION file,
  package-lock.json, and the payload's PS5UPLOAD2_VERSION define.
• Includes all v4.3.1 fixes (cheat engine crash fix).
