Enhancement: Better auto-registration support for ReScript and transpiled components

[justin808]

Summary

The auto-registration feature requires manual wrapper components for transpiled languages like ReScript. Components compiled to .bs.js files cannot be directly auto-registered via the ror_components convention.

Current Workaround

Create JavaScript wrapper files in ror_components/:

// bundles/comments/rescript/ReScriptShow/ror_components/RescriptShow.jsx
import RescriptShow from '../ReScriptShow.bs.js';
export default RescriptShow;

Proposal

1. Extended file extension support: Allow configuration of additional extensions for auto-registration (e.g., .bs.js, .res.js)

2. Resolution alias: Support aliasing patterns in component discovery:

   config.component_resolution = {
     '.bs.js' => :auto_register,
     '.res.js' => :auto_register
   }

3. Documentation: Add guidance for ReScript, TypeScript, and other transpiled component integration

Environment

• React on Rails v16.2.1
• ReScript v11+ (uses .res.js extension convention)
