dns setup

Plan or apply CoreDNS setup for unicast DNS-SD discovery.

Options:

• --domain <domain>: wide-area discovery domain (for example openclaw.internal)
• --apply: install or update CoreDNS config and restart the service (requires sudo; macOS only)

What it shows:

• resolved discovery domain
• zone file path
• current tailnet IPs
• recommended openclaw.json discovery config
• the Tailscale Split DNS nameserver/domain values to set

Notes:

• Without --apply, the command is a planning helper only and prints the recommended setup.
• If --domain is omitted, OpenClaw uses discovery.wideArea.domain from config.
• --apply currently supports macOS only and expects Homebrew CoreDNS.
• --apply bootstraps the zone file if needed, ensures the CoreDNS import stanza exists, and restarts the coredns brew service.
