deploy runs build then push, which is the whole workflow on a local build
machine. It resolves the build host before building so a missing --host fails
in a second rather than after a long compile.
--host now overrides $OMARCHY_BUILD_HOST and .build-host on deploy, push, and
the build trigger in omarchy-pkgs release, so a server can be named per
invocation without arming the release auto-trigger.
