Ink content-sizes the position:absolute, auto-width static box: Static.tsx
sets `{position:'absolute', flexDirection:'column', ...customStyle}` with no
width, ink.tsx calculateLayout never sets the static node's width, and
renderer.ts reads node.staticNode.yogaNode.getComputedWidth() — the computed
width of a yoga absolute, auto-width node, which shrinks to its CONTENT. So
flex-fill children (Spacer/flexGrow/justifyContent/percent) inside a Static
item collapse to content width instead of expanding to the terminal width.
The G44 fix over-forced the iso root to full terminal width (setWidth(columns)),
so a Spacer/flexGrow child expanded to fill the terminal. This refines G44: for
an AUTO-width static node we now leave the iso root width auto and cap it at the
available columns with setMaxWidth(columns), content-sizing exactly like Ink
while still wrapping anything wider than the terminal. The explicit-width
(POINT/PERCENT) copyStyle path from G44 is unchanged and still wins.
Verified against the built Ink reference (v7.0.4, 40b3a75): a Static item Box
row [LEFT][Spacer][RIGHT] at cols=80 renders "LEFTRIGHT" (Spacer collapses),
and [A][flexGrow][B] renders "AB".
