The home daemon now brokers cross-daemon create/kill itself, so the CLI only falls back to the legacy registry HTTP path when the home daemon is *unreachable* — not on 501/404. Removes the now-dead `is_remote_op_unsupported` / `is_not_found` / `has_status` predicates. Adds an e2e (real tmux, two daemons + registry): POST to alpha with daemon_id=beta brokers the create to beta and returns beta's session; a kill via alpha reaches beta. Both verified against the registry catalog. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
