Figures 3 and 4: fix aspect ratio (fig3 was squeezed strip) and key-finding label overlap (fig4)

Per user feedback:
- fig4_penalty_rescue.pdf (Figure 3 in paper): was figsize=(13, 3.5), aspect 3.7:1,
  which rendered as a thin strip with squeezed subplot content. Increased height
  to figsize=(13, 6.0), aspect 2.2:1. Much taller panels that actually show axis
  labels and legends readably.
- fig5_cross_arch_summary.pdf (Figure 4 in paper): the 'Key finding' italic text
  annotation at y=-1.0 in axes transform was overlapping with the multiline
  architecture y-tick labels at the bottom of the second subplot. Moved to
  y=-1.55 and increased figsize height from 3.5 to 4.2 so the lower annotation
  still fits in bbox_inches='tight' crop.
- Also bumped includegraphics width from 0.92\linewidth to \linewidth for both
  figures so they use the full text width.

Main content still exactly 9 pages within E&D budget.
