v0.8.0

Added

• Word-level ("intraline") diff highlighting: within a modified line paired with
  its replacement, only the changed words get a brighter background tint on top
  of the base add/remove tint, so a one-word change no longer reads as a
  whole-line change (like delta's minus-emph/plus-emph). Applies to both
  the unified and split diff views.

Changed

• Diff line-number gutters now tint green/red on added/removed lines (matching
  the sign color) instead of a flat gray, closer to how pagers like delta
  color their line-number columns.
