Migrate symbols.png from 2048x2048 to 4096x4096 layout and add CJK characters.

Old 2048x2048 Layout:
- Rows 0-1535 (1536px): Sprite region, 6 rows × 8 blocks = 48 blocks, 12288 sprites
- Rows 1536-2047 (512px): TUI (blocks 48-52) + Emoji (blocks 53-55)

New 4096x4096 Layout (10 Sprite Rows):
- Rows 0-2559 (2560px): Sprite region, 10 rows × 16 blocks = 160 blocks, 40960 sprites
- Rows 2560-3071 (512px): TUI (blocks 160-169, x=0-2559) + Emoji (blocks 170-175, x=2560-4095)
- Rows 3072-4095 (1024px): CJK region, 128×32 grid, 4096 chars

Usage:
    python migrate_texture.py [options]

Options:
    --input PATH      Input 2048x2048 texture (default: assets/pix/symbols.png)
    --output PATH     Output 4096x4096 texture (default: assets/pix/symbols_4096.png)
    --font PATH       TTF font for CJK rendering (default: auto-detect)
    --chars PATH      File with CJK characters to render (default: built-in common chars)
    --no-cjk          Skip CJK rendering
    --preview         Generate a preview image showing regions
