static: `URL.port` and `URL.hash` have no lowering (`not-implemented`)

[HagegeR]

Summary

The static URL lowering supports protocol, pathname, href, host, hostname, search, searchParams and toString() (per the compiler hint), but port and hash are not-implemented in node-v24-internal.json. Both are needed to validate that a URL is exactly <scheme>://<host>[:port]/<path> with no fragment, which is a typical allow-list check for loopback broker or callback URLs.

Reproduction

// url.ts
const url = new URL("https://example.com:8443/path#frag");
console.log(url.port, url.hash);

$ node --experimental-strip-types url.ts
8443 #frag
$ scriptc build -o /tmp/r url.ts
url.ts:2:13 - error SC2020: 'URL.port' is typed by @types/node but has no scriptc lowering yet
1 error.

With url.port removed the same file reports 'URL.hash' is typed by @types/node but has no scriptc lowering yet. Without a tsconfig.json the ambient URL type lacks both properties (Property 'port' does not exist on type 'URL').

Expected

WHATWG semantics as in Node: port is "" when the port is the scheme default or absent, otherwise the decimal string; hash is "" when there is no fragment, otherwise "#" plus the fragment. Read-only getters are sufficient for my use; setters are a separate ask.

Tier

Static. I have not checked whether the dynamic island exposes them; the request is for the static lowering only.
