# Gitea Actions : pipeline de release (issue #42).
#
# Sur chaque tag v* : construit les binaires de toutes les plateformes,
# archive + publie la release Gitea avec les artefacts. Les installateurs
# (install.sh / install.ps1) et 'am self-update' consomment ces artefacts.
#
# Labels de runners attendus : ubuntu-latest, windows-latest, macos-latest.
# Un runner manquant laisse son job en attente ; le job linux couvre la
# majorite des cas (les artefacts windows/macos peuvent aussi etre produits
# par les scripts locaux documentes dans RELEASING.md).
#
# Prérequis du runner : pouvoir tirer les images docker.io (rust:1.94-alpine,
# ~300 Mo) et le secret GITEA_TOKEN (jeton avec droit 'write:release')
# positionné sur le dépôt. La release existante est écrasée
# (release_overwrite).
#
# Note disque (runner avec espace limite) :
# - il faut ~1 Go libres sur / pour tirer l'image (rust:1.94-alpine) ;
#   en cas de 'no space left on device' : docker system prune -af --volumes
#   sur l'HOTE du runner (pas une autre machine !) ;
# - les builds compilent dans CARGO_TARGET_DIR=/tmp (hors du volume
#   workspace) avec l'incremental desactive, donc rien ne persiste ;
# - le job linux utilise cargo-zigbuild : zig (~50 Mo) fournit le linker
#   croise pour les DEUX cibles musl statiques dans une seule image legere
#   (rust:1.94-alpine n'embarque pas de compilateur croise aarch64).
