fix(supabase): resolve jsDelivr CDN ESM import failure

[mandarini]

Summary

Fixes jsDelivr CDN imports failing with Cannot read properties of null (reading 'AuthClient') since v2.86.1.

Problem

PR #1914 changed wrapper.mjs to import from the CJS build (../main/index.js) and manually destructure 46 exports. When jsDelivr bundles this:

1. Rollup transforms CJS require('@supabase/auth-js') → import default from '@supabase/auth-js'
2. auth-js has no default export, so Rollup adds export default null
3. Destructuring AuthClient from null throws

Solution

Rewrite wrapper.mjs to use direct package re-exports

This approach:

• Uses export * for automatic sync (no manual maintenance)
• Works with jsDelivr (bundles see named exports, not CJS default imports)
• Works with Node.js, esm.sh, and all bundlers
• Reduces wrapper from 95 lines to 22 lines
