# Gitea Actions : pipeline de release (issue #42).
#
# Sur chaque tag v* : construit les binaires de toutes les plateformes.
# Le job principal 'release' cross-compile Linux + Windows depuis un seul
# runner ubuntu-latest, donc il n'a pas besoin de runners Windows/macOS.
# Le job 'macos' est optionnel : s'il y a un runner macos-latest, il ajoute
# les archives macOS a la release existante ; sinon l'installateur retombe
# sur cargo install --git sur macOS.
#
# Les installateurs one-liner (install.sh / install.ps1) et 'am self-update'
# consomment les artefacts attaches a la release.
#
# Cross-compilation utilisee :
#   - Linux x86_64 + aarch64 : cargo-zigbuild + musl (binaires statiques)
#   - Windows x86_64         : mingw-w64 + x86_64-pc-windows-gnu
#
# Prerequis du runner : pouvoir tirer l'image docker.io (rust:1.94-bookworm,
# ~1,2 Go) et le secret GITEA_TOKEN (jeton avec droit 'write:release')
# positionne sur le depot.
#
# Note disque (runner avec espace limite) :
# - il faut ~2 Go libres sur / pour tirer l'image (rust:1.94-bookworm) ;
#   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 ;
# - zig (~50 Mo) fournit le linker croise pour Linux.
