* Add createNode(preset, mode, overrides, additions) nim api * Set p2pTcp/discv5Udp/websocket ports to 0 (auto-bind) in new createNode() * Soft-deprecate --cluster-id=N triggering the associated preset selection * Rewrite applyNetworkConf to apply user-set fields over preset fields * Generate WakuNodeConfOverlay (all Option fields) from WakuNodeConf * New parser for configJson handles new messaging shape and full conf shape * Change all confbuilder defaults from literal values to DefaultXXX consts * Change int/bool WakuNodeConf fields to Option to get user intent w/o sentinels * Make Option CLI default-value help mention defaults now owned by confbuilder * Misc refactors, fixes * Add tests
