docs: Documentar soporte UTF-8 en renderizado de texto
...
- REFERENCE.md: Nueva sección "UTF-8 Text Rendering" explicando:
- Cómo funciona la decodificación UTF-8 → Latin-1
- Caracteres soportados (ASCII + Latin-1 Supplement)
- Por qué UTF-8 es el estándar correcto para BD/archivos
- Ejemplo de uso con texto español
- software.zig: Doc comments explicando el sistema UTF-8
El renderer ahora maneja texto UTF-8 automáticamente,
permitiendo mostrar correctamente: ñ, á, é, í, ó, ú, ¿, ¡, €, etc.

fix(render): Decodificar UTF-8 correctamente en drawText
...
El renderer iteraba byte por byte, causando que caracteres UTF-8
multi-byte (como ñ, á, é) se mostraran incorrectamente.
Cambios:
- Decodificación completa de UTF-8 (1-4 bytes)
- Mapeo de codepoints a Latin-1 para renderizado
- Caracteres fuera de Latin-1 se muestran como '?'
Esto permite mostrar correctamente texto en español y otros
idiomas europeos que usan caracteres Latin-1.
