name: Release

# Workflow standalone — gira nel repo shared-actions stesso.
# Trigger: git tag v* (es. v1.0.0, v1.1.0)
#
# Uso:
#   git tag v1.0.0
#   git push origin v1.0.0
#
# I consumer dei workflow riutilizzabili possono poi usare:
#   uses: https://gitea.com/Punga78/shared-actions/.gitea/workflows/quality-gates.yml@v1.0.0
# oppure il tag major floating (aggiornato ad ogni release):
#   uses: https://gitea.com/Punga78/shared-actions/.gitea/workflows/quality-gates.yml@v1

  push:
    tags:
