[BUG] tsgo list more files than tsc

[HananoshikaYomaru]

Can you confirm that the file lists between tsc --listFilesOnly and tsgo --listFilesOnly match?

If a file is not in that list, it should be impossible for its contents to be used.

for me, no they do not match

how to troubleshoot further.

version of tsgo: @typescript/native-preview@7.0.0-dev.20251219.1
version of typescript: typescript@5.9.3
