Subject: [PATCH] fix(packaging): add `exports` map so default import works
 under Vite/Vitest
MIME-Version: 1.0

Fixes #1654.

v10.0.0 added `"type": "module"` to package.json but kept `main`
pointing at the UMD bundle (`dist/auth0.min.js`) without an `exports`
map. Bundlers that respect `"type": "module"` (Vite, Vitest, modern
esbuild) load the UMD file as ESM and find no top-level `export`
statements — so `import auth0 from 'auth0-js'` resolves to `undefined`,
breaking the documented `new auth0.WebAuth(...)` / `new auth0.Authentication(...)`
usage shown in the README.

This commit adds an `exports` map so each environment receives the
right bundle:

  - `import`  → `dist/auth0.min.esm.js` (real ESM exports)
  - `require` → `dist/auth0.min.js`     (UMD; Jest-style transformers
                                         handle the `exports.X = ...`
                                         writes correctly)
  - `default` → `dist/auth0.min.esm.js` (fallback)

`./dist/*` and `./build/*` wildcards preserve any deep-path imports
consumers may have adopted as workarounds. `./package.json` is exposed
explicitly for tools that read it.

Verified locally:

  - `npm run lint`                  clean
  - `npm run build`                 produces all 4 expected artifacts
  - `npm test`                      658 passing
  - `npm run test:es-check:es5`     pass
  - `npm run test:es-check:es2015:module`  pass
  - Resolution probe under Node 22:
      `import auth0 from 'auth0-js'`                       → object with `.Authentication`/`.WebAuth`
      `import auth0 from 'auth0-js/dist/auth0.min.esm.js'` → same (deep-path workaround preserved)
