libghostty v0.0.10

Breaking

• Position coordinates: cursor and grid lookup APIs use Position
  values. GridRef.positionIn() replaces pointIn(), and GridRef
  no longer needs dispose().

Added

• Selection APIs: Selection, SelectionGesture, active terminal
  selection, and selection formatting expose libghostty selection behavior.
• Tracked grid references: TrackedGridRef follows a cell across
  terminal mutations until the referenced cell is discarded.
• Terminal APIs: working-directory changes, device attributes queries,
  default cursor blink, and Glyph Protocol toggling are exposed.
• Render selection metadata: RowIterator.selection and
  CellIterator.isSelected
  expose row-local selection state for render snapshots.
