feat(build-server): build crystal binaries statically on home.server

The 2022 binaries link libpcre.so.3, which Debian 13 no longer ships.
crystal now comes from the openSUSE repo of the node's Debian release
and links with --static, so the result runs on any release; the build
runs locally instead of cross-compiling through the build-agent.
