DBZ BT4 2.5.5 — lighter ki effects

What's new

Lighter ki effects. The 2.5.1 fix for the grey blocks around ki sparks cost those textures their reuse: they were decoded and sent to the GPU again every frame. On a fast PC that fit in the frame time; on slower ones the 60 fps fight dropped frames (an M2 Pro fell to 47-50 fps). They are now recognised by their content and reused, so the renderer does less per frame than before 2.5.1. In the Gekiretsu Madan test, per frame: texture decodes 55 → 15 and frame recording 3.6 → 3.0 ms. The sparks stay clean.

Online: nothing in the game state changed; plays with 2.4 / 2.5 players and the Mac app.

macOS: DBZ_BT4_Mac.zip is the Mac app 3.4.3 (unchanged).

You need your own ISO (SLUS-219.78, Beta 14 Rev2); nothing from the disc is included.

Build notes: patches/bt3recomp-bt4mod-kispark2.patch (docs/BUILDING.md).
