Build and Publish Docker Image #3

# OpenTracker API - Docker Image Build & Publish
# Este workflow construye y publica la imagen Docker en GitHub Container Registry
# Se ejecuta automáticamente cuando se crea una nueva release
#
# Usa matrix strategy con runners nativos para builds multi-plataforma rápidos:
# - linux/amd64 se construye en ubuntu-latest (x86)
# - linux/arm64 se construye en ubuntu-24.04-arm (ARM nativo)
