fix(discovery): only accept STATUS messages on discovery channel#133

A peer can reply with a HelloMessage on a discovery probe channel to trick the node into running the full handshake path: the channel ends up in ChannelManager.channels, onConnect fires, and finishHandshake is set, polluting the connection table and consuming a maxConnections slot. Guard processMessage so a channel in discoveryMode only accepts STATUS and is closed otherwise.

What does this PR do?
Discovery probe channels accept any message, letting a peer's HelloMessage trigger the full handshake and consume a maxConnections slot. Restrict discoveryMode channels to STATUS only.
