Menu Customizer 3.35.25 - Matrix rain and menu cleanup

• Add Matrix rain as both a border and a background: Green, Cyan, Violet,
  Spectrum and Amber, with animated color gradients and existing speed controls.
• Remake Black Waterfall with continuous falling lanes, spray and repeating
  pools across the full display, including 32:9 ultrawide screens.
• Remove preset themes and static Pokemon backgrounds from the pickers.
  Consolidate similar static colors. Saved numeric IDs remain stable and
  retired colors/backgrounds resolve to retained choices.
• Add independent Bag and Party font, background, border, text/shadow,
  selector and text-effect controls, including the native Hoenn screen paths.
  Global controls include these screens; USE MENU STYLE restores inheritance.
• Fix SAVE fade restarts when GB/GBC dialog children change, preserve GBA
  transitions across missed presentation frames, and isolate offscreen replay
  from inherited clipping, color, blend and stencil state.

Built from GitHub v3.35.24. Validation: all eleven games pass Loader/settings
and native Bag/Party GPU fixtures on engine 0.3.95. Desktop and GLES shaders,
five Matrix variants with independent border motion and speed controls,
32:9 waterfall coverage/motion, and 12 stable SAVE replay frames pass. The
SAVE rendering regression fails on v3.35.24 and passes with this update.
Validation uses native constructed fixtures, not a full gameplay playthrough
or a physical Android device. No custom launcher is required.
