Fix Windows CI build warnings and missing system libs

[Copilot]

The Windows CI build failed due to MSVC size-conversion warnings and unresolved external symbols from missing system libraries. Linker errors hit token/COM APIs and formatting helpers, blocking the executable output.

• Linker dependencies

  • Add explicit pragma links for advapi32, ole32, and user32 to resolve missing symbols.

• Size safety + buffer handling

  • Replace lossy size_t→DWORD/ULONG conversions with checked bounds and clearer buffer sizing in rename and reparse flows.
  • Free rename buffer after NtSetInformationFile use to avoid leaks on the success path.

• Time conversion clarity

  • Normalize FILETIME→ULARGE_INTEGER handling and label the 5-second 100ns offset.

Example change:

const size_t tmp_len = wcslen(_tmp);
if (tmp_len > (ULONG_MAX / sizeof(wchar_t))) {
    printf("Rename filename length exceeds maximum size.\n");
    return 1;
}
const size_t tmp_bytes = tmp_len * sizeof(wchar_t);
if (tmp_bytes > (ULONG_MAX - sizeof(FILE_RENAME_INFORMATION))) {
    printf("Rename buffer size exceeds maximum limit.\n");
    return 1;
}
