Subject: [PATCH] ci: give the release link swap on GitHub runners

The v2026.9.30 tag build's arm64 publish job was killed linking the
inbuxa binary (fat LTO, one codegen unit): cannot allocate memory on the
16 GB ubuntu-24.04-arm runner. index, ghcr, release, binaries and
announce were skipped. amd64 got through on the same size of runner.

Each publish job now adds a 16 GB swap file before the build; buildx's
container has no memory limit of its own, so the linker can use it.
