Grind main/menu_item: 97.234% -> 97.350% (cast/schedule named-temp)

[asmithbot]

Summary

ItemDraw: factor (float)(1.0/duration) into a named local widthFrac before multiplying by (float)entry->w.

This mirrors the Ghidra ground truth (80159df4_ItemDraw__8CMenuPcsFv.c lines 134-135):

in_f29 = (double)((float)(DOUBLE_80332e68 / (local_b0 - DOUBLE_80332ea0)) *
                  (float)(local_b8 - DOUBLE_80332ea0));

The named temp forces the division/frsp to be materialized before the w-bias fsubs, matching the target instruction schedule. Value-identical, behavior-safe.

Gate

• ItemDraw misalign 9 -> 7 (matched rows realigned: frsp/fsubs order)
• unit main/menu_item fuzzy_match_percent 97.234 -> 97.350
• No function regressed (ItemInit 13, ItemCtrlCur 2, ItemInit1 1, others 0 all unchanged)
