feat: automate multi-arch image builds on release via QEMU
Replace native arm64 runners (unavailable on free tier) with QEMU
emulation. All three image builds now trigger automatically on
`release: published`, deriving version and :latest flag from the
GitHub release event. workflow_dispatch retained for manual rebuilds.
