Release v1.6.55

- Replace extractSlow() per-item extraction with IInArchive.extract() bulk API
  in 7-Zip-JBinding. Solid RAR archives no longer re-decode from the beginning
  for each item, bringing extraction speed close to native WinRAR/7z.exe (~375 MB/s
  instead of ~43 MB/s).

- Add BulkExtractCallback implementing both IArchiveExtractCallback and
  ICryptoGetTextPassword for proper password handling during bulk extraction.

- Fix resolveArchiveItemsFromList with multi-level fallback matching:
  1. Pattern match (multipart RAR, split ZIP/7z, generic splits)
  2. Exact filename match (case-insensitive)
  3. Stem-based fuzzy match (handles debrid service filename modifications)
  4. Single-item archive fallback

- Simplify caching from Set+Array workaround back to simple Map<string, T>
  (the original "caching failure" was caused by resolveArchiveItemsFromList
  returning empty arrays, not by Map/Set/Object data structure bugs).

- Add comprehensive tests for archive item resolution (14 test cases)
  and JVM extraction progress callbacks (2 test cases).
