fix(coverage): exclude scripts with invalid URLs from raw coverage output (#28210) Fixes https://github.com/denoland/deno/issues/28206. Basically if you execute a script with `node:vm`, this produces a "script" with the file name `evalmachine.<anonymous>`, which ends up producing coverage like ```json { "scriptId": "319", "url": "evalmachine.<anonymous>", "functions": [ { "functionName": "", "ranges": [{ "startOffset": 0, "endOffset": 18, "count": 1 }], "isBlockCoverage": true } ] } ``` We assume that the `url` field here (the specifier of the script) is a valid URL, and so we error out when processing that coverage. There are two potential fixes: either don't write the coverage files for those scripts, or ignore the errors when we process the data. I went with the former here. 2025-02-20 14:23:43 -08:00			`import { foo } from "./main.ts";`
