Subject: Use portable file ownership for transcript reads

Replace the Windows-only LLUniqueFile with std::unique_ptr and the
existing LLFile::close deleter. This fixes the macOS compile failure
while retaining automatic file closure on every exit.

Windows Release build, 41 history tests, and repository hooks passed.
macOS CI still needs to be rerun.
