svelte-package missing type definitions and type duplicates

Describe the bug

If you create a component ex. Example.svelte and a svelte-file ex. example.svelte.ts it won't generate a example.svelte.d.ts causing type errors;

If you create a class ex class Example and import that into a file with the same name Example.svelte ― it will have duplicate types after svelte-package

Additional Information

1st needs (perhaps) to be case-sensitive when checking if file exists.

2nd I think might inquire a warning, as I did do local testing on the library with no issues, published it, only for it to be "unusable" when I put it into use in a different project (ex. svelte-tably).

(Which is a shame, because svelte-tably is my hackathon entry and I cannot make changes to it🤣)

Start with the linked Refzlund/svelte-package-bug reproduction and the svelte-package entry point, focusing on the two reported cases: a .svelte.ts file without a generated declaration and duplicate types from matching class and component names. Done means the reproduction produces the expected type definitions without duplicates or resulting type errors.
