Subject: [PATCH] fix: also pin emulators pathPrefix to 8.3.14
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

js-dos 8.3.14 hardcodes pathPrefix default to 'latest/emulators/'
internally, so pinning the JS file alone still loads the BROKEN
emulators 8.3.8 wlibzip.wasm. Must also pass pathPrefix.

Verified on CDN:
  8.3.14/emulators/ → emulators 8.3.3, wlibzip.wasm 112,732 bytes ✓
  latest/emulators/  → emulators 8.3.8, wlibzip.wasm 113,081 bytes ✗
