Plan-graph refinement round 7 (owner): no fly-in on open, nodes never truncate

Fly-in, take two: round 4 kept settled OFF until the first fit, but the
flag flipped in the SAME commit as the transform change — the browser saw
the new transform + newly-added transition in one style update and
animated from the initial top-left zoom:1 state. The transition now
enables one paint AFTER the fit (requestAnimationFrame), so the popup
opens settled and only glides for user input afterwards.

Nodes show their FULL content (owner): wrapTitle no longer caps lines
or ellipsizes — oversized words are hard-chunked, nothing is dropped.
Boxes grow with their wrapped lines (NODE_H + LINE_H per extra line);
layout rows take their tallest node, edges leave from the source's real
bottom, the glow rect and the plan-window's centering follow the grown
height, and the text block centers in the grown box.
