Subject: [PATCH] fix: disable modulePreload polyfill for Chrome MV3
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Vite was injecting modulepreload-polyfill.js into the built output, which
Chrome rejected at runtime with: 'A preload for .../modulepreload-polyfill.js
is found, but is not used because it is a cross-world extension resource
mismatch.'

Disabling the polyfill (extension context does not need it — Chrome 110+
supports bare ESM natively) removes the offending chunk entirely.
