Merge pull request 'fix(engine): resize pile-marker outline and watermark children on relayout' (#131) from fix/pile-marker-child-resize into master

Found during Fold 7 on-device verification of v0.41.0: on_window_resized
resized the marker fill sprite but never its children, so after any
resize (fold/unfold, rotation) the outline frame and the A/K watermark
kept their spawn-time size — rendering as oversized grey slabs over the
empty foundation slots.

The resize handler now re-derives both children from the new layout
(outline = card_size + 2*PILE_MARKER_OUTLINE_WIDTH, watermark font =
card_size.x * 0.28 — same formulas as spawn). Adds a regression test
and an Android-gated relayout log line (width/height/insets) as the
evidence channel for the remaining foldable layout bug (#130).
