feat: AsicCreateResult.FileNames for ASiC-E containers #9
Description
Summary
AsicCreateResult currently has DataHash which for ASiC-E is the manifest hash — but no list of file names or per-file hashes. A consumer calling CreateExtendedAsync has no way to see which files were included or their individual hashes without parsing the ASiCManifest XML themselves.
Proposal
Add to AsicCreateResult:
FileNames(IReadOnlyList<string>?) — populated for ASiC-E, null for ASiC-S- Optionally
FileHashes(IReadOnlyDictionary<string, string>?) — per-file hex hashes
This mirrors AsicVerifyResult.FileNames which already exists on the verification side.
