| # 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) | |
