v0.8.0

.gtui format 9 (reads v1..v9). Crate 0.8.0.

Changed

• Keyboard cursor movement scrolls like nvim: the view stays put until the cursor reaches a
  two-cell margin, then every further step scrolls the picture by exactly one cell immediately
  while the cursor keeps its screen line (only its logical cell advances). Scrolling here is
  not eased — an animation would move the cursor down one cell and then pull it back, which reads
  as a jump. Jumps (search, n / N, click, jump history) stay animated, and all mouse gestures
  are unchanged.

Fixed

• A point-node edge no longer routes straight along an edge that is already drawn: two edges that
  occupy the same cells collapse into one stroke, so the later edge looks invisible while the
  earlier one's arrowhead sits on it, which makes the selected edge read as bidirectional. The L
  now picks the other corner when the first one would duplicate an existing run of the same axis
  (crossings still share a single cell, as before).

• Edges keep their shape while the view moves: routing now looks at the whole document
  (every node is an obstacle, and the "this cell already has a stroke" state is kept outside the
  viewport too) instead of only at the visible cells, so panning and cursor scrolling are a pure
  translation of the picture and a long edge whose node has left the screen still shows the part
  that is on screen.

• Ctrl-o / Tab (Ctrl-i) walk a proper jump list: besides search hits, n / N and mouse
  clicks, every edit records its position — creating a box, editing text, changing a style — while
  plain cursor moves do not. Ctrl-o from anywhere first notes where you are and then goes back to
  the last place you worked.

Added

• Six hand-placed joke graphs under examples/fun/ (owl, left-pad, git-graph, unix,
  invaders, dynasties), listed in docs/examples.md. They use geo layout, so the stored
  coordinates are the picture; invaders is pure pixel art built from 46 single-cell text boxes,
  and dynasties is a 44-regime top-down Chinese-dynasty DAG of point nodes with one-line CJK
  labels placed around them: edges branch where regimes coexisted and merge where one power
  reunified, with no edge labels. The
  native example test walks examples/fun/ as well.
• <|new box|> inside the text prompt splits one box into several: the text before the marker
  stays in the box, each following segment becomes a new box to its right (top aligned, one cell
  apart, nudged right/down when the space is taken) that copies the source box style, colours,
  fill, text alignment and layer. Edges and notes stay on the original box; the cursor does not
  move and the whole split is one undo step. Only single plain boxes split: multi-selections, edge
  notes and point nodes keep the marker as ordinary text, and so do :text and headless text.
  \<|new box|> is a literal.
