Initialize Node for Federation Network

Initialize this node for federation. Generates an ed25519 keypair, creates the federation config, and optionally sets a compliance mode.

Steps:

1. npx -y -p @claude-flow/plugin-agent-federation@latest ruflo-federation init
2. If a compliance mode is specified, configure it: npx -y -p @claude-flow/plugin-agent-federation@latest ruflo-federation config --compliance MODE
3. Show the node's public key and endpoint for sharing with peers

Store init event: mcp__claude-flow__memory_store({ key: "federation-init", value: "Node initialized", namespace: "federation" })
