fix(deploy-node): resolve HOST_DIR via os_hostname lookup, not bare hostname

Replaces the brittle `hosts/$(hostname|lower)` assumption with a scan
of hosts/*/host.yaml for a matching os_hostname field. This fixes VPS
where the OS hostname (ubuntu-4gb-hel1-1) never matched the repo
directory (hosts/vps/), causing a silent "No services found" false-green.

Fallback to lowercase-hostname dir preserved for nodes that haven't yet
received the os_hostname field; exits 1 with a clear message if neither
match nor fallback directory exists.
