Subject: [PATCH] fix: add .js extensions to imports for Node.js ESM
 compatibility

Add explicit .js extensions to all local imports to ensure the compiled
output works correctly in Node.js ESM environments (e.g., Vitest with
moduleResolution: 'bundler').

This follows the TypeScript recommendation for libraries:
https://www.typescriptlang.org/docs/handbook/modules/guides/choosing-compiler-options.html#im-writing-a-library

Fixes NEO-935
