fix(remote): refresh wake command from host config when restoring sessions

A session's remote block is persisted at launch time and recovery uses that
snapshot, so a wakeCommand added to remote-hosts.json afterwards never reached
an already-running session - not even across a Codeman restart (observed: the
live Hufflepuff session came back with no wakeCommand). Merge the host-level
field in on restore, with the host config authoritative.
