KeibiDrop v0.3.6

Faster streaming and edit sync over slow or distant links, plus
fresh-install and read-reliability fixes.

• Smoother large-file streaming over slow or distant links: on-demand
  reads now look ahead and keep upcoming blocks in flight, so video and
  long sequential reads no longer stall at each 16 MiB boundary. On by
  default and self-tuning.
• Faster edit sync: when a peer changes part of a file, only the changed
  pieces are re-fetched instead of the whole file.
• Quicker reconnects: the shared-folder cache is kept across a disconnect
  and reused when the same peer reconnects, so you don't re-download what
  you already have.
• Fresh-install fixes: internet mode now connects out of the box and
  "Open Folder" opens the real mount instead of the working directory.
  The relay, ports, and mount path all come from one source of truth.
• Steadier reads: a brief transfer failure no longer looks like the end
  of the file, so readers and media players don't see a truncated file.
• Windows: a launcher script pins a consistent mount drive so the mount,
  "Open Folder", and the displayed path always agree.

Platforms: Windows (x86_64), macOS (arm64, x86_64), Linux (x86_64)
