# ─────────────────────────────────────────────────────────────
# Haven — Automatic Docker Image Build & Publish
# Triggers on every GitHub Release (tag push).
# Pushes to GitHub Container Registry (ghcr.io) — free, unlimited
# for public repos, no account caps, no manual steps needed.
#
# Builds amd64 and arm64 on separate NATIVE runners (no QEMU),
# pushes each as a digest, then merges into a multi-arch manifest.
# Native builds are required because better-sqlite3 compiles a
# native C++ addon — QEMU emulation is too resource-constrained
# and causes intermittent SIGILL/OOM failures during npm ci.
