`@wry/caches` is not compatible with `moduleResolution = node16`

Trying to use @wry/caches in a package with moduleResolution set to node16 (or nodenext) fails with the errors:

node_modules/@wry/caches/lib/strong.d.ts:1:34 - error TS2835: Relative import paths need explicit file extensions in ECMAScript imports when '--moduleResolution' is 'node16' or 'nodenext'. Did you mean './common.js'?

1 import type { CommonCache } from "./common";
                                   ~~~~~~~~~~

node_modules/@wry/caches/lib/weak.d.ts:1:34 - error TS2835: Relative import paths need explicit file extensions in ECMAScript imports when '--moduleResolution' is 'node16' or 'nodenext'. Did you mean './common.js'?

1 import type { CommonCache } from "./common";

Thanks for raising this. I just observed the same error, but with @wry/caches as a transitive dependency of @apollo/client. I'm still a bit confused because normally this error would only affect the package being built, not its dependencies. For reference, the TypeScript version being used here is 5.7.3.
