chore: tests for ast-manipulation

[manuel3108]

This adds initial testing capabilities to ast-manipulation

Things to consider:

• adding / comiting empty input.ts files is probably useless. Removing them on the other side could cause confusion why some files have that file and some do not
• Those tests are pretty basic. The goal here was not test everything but rather to provide a good basis. Adding new tests should be straightforward.

Todos:

• tests for html utilities
• tests for css utilities
• fix default-export test
• fix named-export test
• fix named-import-merging test (@AdrianGonz97 didn't you worked on that in the past? Would you mind linking / contributing the relevant code?)

Thanks, that indeed fixes the test.

overall, this looks really good! just a few minor changes are needed.

adding / comiting empty input.ts files is probably useless. Removing them on the other side could cause confusion why some files have that file and some do not

im in two minds about this. on one end, i get it for the sake of consistency. on the other, it does needlessly clutter up directories.

i think im leaning more towards the latter, though. we'll be alright if they're deleted

perfect!
