v0.2.1

Changed

• Speed up opening large interactive diffs by streaming unified patch parsing
  into the TTY model, sharing diff text between layouts, and capping eager
  inline-diff work for very large change sets.
• Open interactive diffs for record-stream inputs lazily, formatting and
  comparing bounded record batches for the first draw while redirected stdout
  still emits the full unified patch.

Fixed

• Soft-wrap long lines in the interactive diff viewer, including side-by-side
  rows, and scroll through wrapped visual rows instead of skipping directly to
  the next diff row.
