Subject: [PATCH] fix(types): allow `false` sentinel in `file_cache` type
 annotation

Problem: lua-language-server reported `cast-local-type` because
`file_cache` was annotated as `table<string, string[]>` but stores
`false` as a sentinel for files that failed to open.

Solution: widen the annotation to `table<string, string[]|false>`.
