rapidgzip-rust v0.2.1

Fixed

• Marker/window resolution waits now drain the bounded speculative-result
  channel. This prevents all shared workers from blocking while publishing
  decode results when the coordinator needs queued resolution work to finish.
• Parallel-encoder sync flushes can no longer force an otherwise suitable
  gzip or zlib stream off the marker/window path. Small discontinuities between
  speculative chunks are exact-decoded with authenticated history and retain
  the existing safe fallback for invalid or larger gaps.
