Module handle 

SSH event handlers: authentication, channels, environment variables.

Every incoming SSH event is dispatched here by the connection loop in serve. The main entry point is session_env, which routes environment variable requests to handlers like pubkey_env, wifi_ap_ssid_env and wifi_sta_ssid_env.

First-boot provisioning also flows through here: when first_login is true, the device accepts any SSH connection (empty password) and allows the client to set SSH_STAMP_PUBKEY. Subsequent connections require that key.
