NativeLibrary.trySkipCache splits ranges larger than Integer.MAX_VALUE before passing them to posix_fadvise, but incorrectly moved the offset backward after each chunk, so page-cache eviction for ranges over 2 GiB targeted the wrong offsets. Advance the offset so all chunks cover consecutive forward file ranges, and add deterministic unit coverage for large, boundary, nonzero-offset, and whole-file ranges.
