93e26d3789 Add mcp dns and mcp node routes commands
mcp dns queries MCNS via an agent to list all zones and DNS records.
mcp node routes queries mc-proxy on each node for listener/route status,
matching the mcproxyctl status output format.

New agent RPCs: ListDNSRecords, ListProxyRoutes.

3d2edb7c26 Fall back to podman logs when journalctl is inaccessible
Probe journalctl with -n 0 before committing to it. When the journal
is not readable (e.g. rootless podman without user journal storage),
fall back to podman logs instead of streaming the permission error.
