Convert library from CommonJS to ES Modules

[endlacer]

Description:
Currently, the library uses CommonJS module syntax (require/module.exports)
WARNING in CommonJS or AMD dependencies can cause optimization bailouts.

Problem:
CommonJS module format is incompatible with modern bundler optimizations (eg Angular)
Prevents effective tree-shaking
Causes decreased performance due to optimization bailouts

Proposed Solution:

• Convert the codebase to use ES Modules (import/export)
• Replace require() statements with import
• Replace module.exports with export/export default
• Update the module resolution in package.json
• Remove IIFEs where present

Expected Benefits:

• Better compatibility with modern bundlers
• Improved tree-shaking
• Elimination of Angular optimization warnings
• Better build performance
