[Website] Run HTTPS test server for tcp-over-fetch-websocket tests

[Copilot]

Motivation for the change, related issues

fetchWithCorsProxy now upgrades HTTP URLs to HTTPS. Tests making requests to http://127.0.0.1:PORT get upgraded to https://127.0.0.1:PORT, requiring an HTTPS test server.

Implementation details

Test server migration to HTTPS

• Generate self-signed certificates with SANs for 127.0.0.1 using selfsigned library
• Convert Express server from app.listen() to https.createServer()
• Set NODE_TLS_REJECT_UNAUTHORIZED=0 for test environment

Fix request body stream handling

• cloneRequest() was calling await request.blob() to clone requests with bodies
• This hung on POST requests because the body stream was still awaiting data that would never arrive
• Solution: Reuse unconsumed body streams directly via request.body instead of reading to Blob

// Before: Hangs when body stream is still open
const body = await request.blob();

// After: Reuses stream when possible
const body = !request.bodyUsed && request.body 
  ? request.body 
  : await request.blob();

• Added duplex: 'half' to Request creation for Node.js streaming body compatibility
• Removed unused @ts-expect-error directive as TypeScript now properly recognizes the duplex property

Testing Instructions (or ideally a Blueprint)

CI. All 31 tests in tcp-over-fetch-websocket.spec.ts pass, including POST requests with bodies.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.cypress.io
  • Triggering command: node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot remove expect error:

packages/php-wasm/web-service-worker/src/utils.ts:196:3 - error TS2578: Unused '@ts-expect-error' directive.
194 | // In Node.js, duplex: 'half' is required when
195 | // the body is provided for non-GET/HEAD requests.

196 | // @ts-expect-error - duplex is not in the TypeScript types

...

Done! Removed the unused @ts-expect-error directive. TypeScript now properly recognizes the duplex property in Request options. (Commit: 94747c8)
