feat: Add JavaScript entry point (replaces main.ts)

Created src/main.js as pure JavaScript wrapper for ReScript modules.
Provides same API as main.ts but without TypeScript (RSR Rhodium R13).

Features:
- ES6 module exports
- JSDoc type annotations for IDE support
- Imports ReScript compiled .bs.js files
- analyze(), analyzeZoteroCollection(), generateReport(), toJson(), generateVisualization()

This maintains zero TypeScript while providing clean external API.
