Release v1.6.46

Release post-process slot immediately after main extraction completes.
All slow post-extraction work (nested extraction, auto-rename, archive
cleanup, link/sample removal, empty directory cleanup, MKV collection)
now runs in background via runDeferredPostExtraction so the next package
can start unpacking without delay.

- Export hasAnyFilesRecursive, removeEmptyDirectoryTree, cleanupArchives
  from extractor.ts for use in deferred handler
- Import removeDownloadLinkArtifacts, removeSampleArtifacts from cleanup
- Expand runDeferredPostExtraction with full post-cleanup pipeline:
  nested extraction, rename, archive cleanup, link/sample removal,
  empty dir tree removal, resume state clearing, MKV collection
