fix: avoid exposing browser-only ESM build via module #237

[lelnotwellyet]

module was pointing to a browser-only ESM build that references indexedDB,
which causes Node.js to throw ReferenceError: indexedDB is not defined in
non-browser environments.

This change removes the module entry to ensure:

• Node.js only resolves Node-safe entry points
• browser bundlers continue to use the browser build

Note: module is valid for Node.js when it points to a Node-safe ESM build.
In this package it currently resolves to a browser-only output, so removing
the entry avoids the runtime crash until a Node-compatible ESM build exists.

Build verification is covered by CI.
