chore: eliminar workflow de Gitea/Coolify

Eliminación del workflow de despliegue automático a Coolify.

El repositorio actualmente no requiere despliegue automático, por lo que se elimina la configuración del workflow de Gitea para simplificar la estructura del proyecto.

+)
+
+requests_total.inc(endpoint="/health")
+latency_seconds.observe(0.35, endpoint="/health")
+```
+Agrega el puerto (`9102` en el ejemplo) como target de scrape en Prometheus/Alloy para ver las series con el prefijo definido.
+
+Atajo: si quieres emitir sin guardar handles, usa `counter_value`, `gauge_value`, `histogram_observe` y `summary_observe`, pudiendo sobreescribir el prefijo por métrica:
+```python
+metrics.gauge_value("workers_active", 3, prefix="backend", labels={"queue": "ingest"})
+metrics.counter_value("processed_total", 1, prefix="backend", labels={"queue": "ingest"})
+```
+
+En este repo, Alloy ya está configurado para scrapear `host.docker.internal:9102` con el `job_name="app_metrics"`. Si tu script expone métricas en ese puerto (con `PrometheusMetric(port=9102)`), se almacenarán sin cambios adicionales.
