feat: add integrity flag support

[guybedford]

Updates to the latest generator.

[JayaKrishnaNamburu]

@guybedford i started looking into this, and the tests are failing from the usage of @babel/core. We get @babel/core@7.24 now from the @jspm/generator. So during the check for type of file. The tests are failing now.
Which is here

const source = await fs.readFile(resolvedModule.target, { encoding: "utf8" });
  const babel = await import("@babel/core");

  try {
    babel.parse(source);
    return resolvedModule; // this is a javascript module, it parsed correctly
  } catch (e) {
    /* fallback to parsing it as html */
  }

https://github.com/jspm/jspm-cli/blob/main/src/link.ts#L130

But seems there is no default exports in node env.
https://codesandbox.io/p/devbox/elated-saha-qw6s77?file=%2Fpackage.json%3A11%2C49

It passes if its changed to named-import here. But then the tracer from @jspm/generator again uses the same approach and the tests fail.

export async function createCjsAnalysis(
  imports: any,
  source: string,
  url: string
): Promise<Analysis> {
  if (!babel) ({ default: babel } = await import("@babel/core"));

  const requires = new Set<string>();
  const lazy = new Set<string>();
  const unboundGlobals = new Set<string>();

  babel.transform(source, {
    ast: false,
    sourceMaps: false,

https://github.com/jspm/generator/blob/main/src/trace/cjs.ts#L24

The one from the generators seems to pass because the project is built using rollup there. And i suspect the behaviour in both the places is little different. Should we switch to named-imports in both the places. Any inputs fro this ?

And btw, the import for @babel/core also seems to fail with import-map now.

@JayaKrishnaNamburu thanks for looking into this. I've pushed a fix for Babel, is it working now for you? You may need to clear your browser cache.

[JayaKrishnaNamburu]

@guybedford the fix for jspm is working good now. Should we switch to namedImports for @babel/core in generator and in the cli. Because the direct import of @babel/core is missing the default export from the package in node env.

[guybedford]

Yes, let's update the generator to use named exports now then?

[JayaKrishnaNamburu]

cool, will update the PR here and make on on the generator for the same 👍

[guybedford]

Let me know if I can help further on this PR at all.
