Add runtime peer management to the FIPS daemon via control socket commands, and a new chaos simulation scenario that exercises dynamic topology mutation with ephemeral node identities. Daemon (connect/disconnect commands): - Extend control socket Request with optional params field - Add commands.rs module for mutating command dispatch, separate from read-only queries - Add api_connect() on Node: builds ephemeral PeerConfig (no auto- reconnect), pre-seeds identity cache, reuses initiate_peer_connection - Add api_disconnect() on Node: calls remove_active_peer(), clears retry_pending to suppress reconnection - Route non-show_* commands to async command dispatch in rx_loop fipsctl CLI: - Add Connect and Disconnect subcommands accepting npub or hostname - Resolve hostnames from /etc/fips/hosts before sending to daemon - Refactor socket I/O into reusable send_request helper Chaos simulator (maelstrom scenario): - Add PeerChurnManager: periodically disconnects a random active link and connects a random unconnected node pair via control socket - Add send_command() to control.py using base64-encoded JSON payloads to avoid shell quoting issues in docker exec - Add PeerChurnConfig to scenario with interval and ephemeral_fraction - Ephemeral identity support: nodes configured without nsec generate fresh keypairs on restart; simulator queries show_status for new npub and updates its cache via on_node_restart callback - Add maelstrom.yaml: all chaos dimensions (netem, link flaps, node churn, peer topology churn, traffic) with 50% ephemeral identity
