fix(netlify): support lambda event requests and cjs cache exports

[azinod]

Summary

This PR fixes two follow-up Netlify runtime regressions we hit while validating the Netlify deploy path after the bootstrap filename fix from #8379:

1.

The first problem was that server-side CommonJS output could end up doing require('@modern-js/runtime/cache'), but the ./cache subpath only exported an ESM target. In a real Netlify function this caused startup to fail with:

Error [ERR_REQUIRE_ESM]: require() of ES Module /var/task/node_modules/@modern-js/runtime/dist/esm/cache/index.mjs from /var/task/server/lib/cache/setup.js not supported.

To fix that, this PR adds a CommonJS-compatible node.require export for @modern-js/runtime/cache and points the default export at the CJS build.

2.

The second problem was in the Netlify request adapter. The generated Netlify handler was forwarding the Lambda-style Netlify event directly into server.handle(...), but Hono expects a real Fetch Request with a url. In production this caused:

TypeError: Cannot read properties of undefined (reading 'indexOf')
    at Hono.getPath (/var/task/node_modules/hono/dist/cjs/utils/url.js:103:21)
    at #dispatch (/var/task/node_modules/hono/dist/cjs/hono-base.js:298:23)
    at Hono.fetch (/var/task/node_modules/hono/dist/cjs/hono-base.js:347:26)
    at /var/task/node_modules/@modern-js/prod-server/dist/cjs/netlify.js:48:39
    at Runtime.handler (/var/task/netlify-handler.cjs:73:24)

To fix that, this PR teaches @modern-js/prod-server/netlify to:

• detect whether it already received a web Request
• otherwise convert the Netlify Lambda event into a Fetch Request
• pass that Request to server.handle(...)
• convert the returned Response back into a Netlify-compatible function response

Together these changes make the generated Netlify function artifact work in the downstream app we used for verification, both locally and in actual Netlify branch deploys.

Checklist

• I have added changeset via pnpm run change.
• I have updated the documentation.
• I have added tests to cover my changes.

Validation

• pnpm --filter @modern-js/runtime build
• pnpm --filter @modern-js/prod-server build
• packed patched local Modern.js packages and consumed them from a downstream app
• verified require.resolve('@modern-js/runtime/cache') resolves to dist/cjs/cache/index.js in the generated Netlify function bundle
• verified the generated @modern-js/prod-server/dist/cjs/netlify.js contains the Netlify event -> Request adapter logic in the downstream app's .netlify/functions output
• validated the generated artifact path through Netlify branch deploys for poc and develop
