fix: Convert all CommonJS to ESM and fix most ESLint errors

- Converted all 25 CommonJS files to proper ESM syntax
- Fixed require() statements to import statements
- Fixed module.exports to export default
- Added .js extensions to all relative imports
- Fixed __dirname usage in ESM files
- Resolved most ESLint errors (down from 900+ to 323)
- All files now use proper ESM syntax

Remaining work: 323 ESLint errors (mostly style issues)
