Bug: npm package does not support esm in nodejs project.

[xianminx]

Describe the bug

My NodeJS project fails to run when type set to module in package.json. The log shows it is caused by redundant module.exports in usearch.js file.

file:///Users/lucas/dev/workspace/gpt/uphoto/node_modules/.pnpm/usearch@2.11.1/node_modules/usearch/javascript/dist/esm/usearch.js:461
module.exports = {
^

ReferenceError: module is not defined in ES module scope
This file is being treated as an ES module because it has a '.js' file extension and '/Users/lucas/dev/workspace/gpt/uphoto/packages/server/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

Node.js v22.2.0

Steps to reproduce

1. create a NodeJS project, setting type to be module in package.json.
2. create a plain index.js.
3. import usearch in index.js
4. run node index.js

Expected behavior

I see usearch.js file supports ESM and CommonJS by writing module.exports and export in the same file.

module.exports should not be included in ESM dist.

Interesting, @xianminx! Seems like it will be fixed by #420, right?

In the esm file, I had to replace

module.exports = {
  Index,
  MetricKind,
  ScalarKind,
  Matches,
  BatchMatches,
  exactSearch,
};

with

const usearch = {
    Index,
    MetricKind,
    ScalarKind,
    Matches,
    BatchMatches,
    exactSearch,
};
export default usearch;

@johnhorsema this seems better, than what we've merged into main-dev. If that's so, can you open a PR?
