Separate cache by architecture

[koterpillar]

Fixes #261

Note that existing caches will become invalid as a result of this change.

I could try to deduce the "default" architecture (likely x64 on Linux runners and arm64 on macOS runners, etc.) if we want to preserve (more of) existing caches.

This looks good, thanks. I guess the test failure was a hiccup, because it passed on retry (and we can ignore the asana one).

Two quick book-keeping things:

1. Can you amend your commit to be fix: separate...?

   We don't require conventional commits generally, but it drives our automatic release, so formatting your commit this way will trigger a release with minor version bump.

2. Please run yarn build and commit the updated dist/index.js

   Do this as its own commit please. We're trying to make this unnecessary, but for boring technical reasons we're not there yet.

Thanks!

[koterpillar]

Done.

Note:

• sed invocation in package.json does not work correctly with macOS version of sed.
• yarn build changed all module identifiers, the build process might not be deterministic across different installs.

Thank you!

changed all module identifiers

😱 is that... OK?

I'm not a JavaScript expert, so I have no idea if this is an issue or how to solve it.

That's not a functional change, see the diff - just some numbers reallocated. Feel free to re-run yarn build yourself if in doubt!
