- waku.nimble: libp2p #f54c7150a7ccbc4e9871bb8b56ecfd7e3e59f7de; also pin protobuf_serialization#ce97ba0 and websock#fb8ba71 to match new libp2p reqs; mix remains on 6c5f43 (its declared pins lag)
- nimble.lock + nix/deps.nix updated (libp2p rev/sha)
- Source fixes for new libp2p (object configs, removed utility module -> libp2p/utils/opt, rendezvous nil, kademlia no longer imports mix_protocol to reduce bad dep surface)
- nph on touched .nim
- chat2disco builds+starts successfully against the updated libp2p (with in-nimbledeps patches to mix for its removed symbols like sequninit/utility and withValue(Opt) sites; run make update will require similar or upstream mix bump)
Refs the 106-commit libp2p delta with kademlia/service-disco fixes (e.g. ticket time, record sizes, registration).
* Rename waku_api to rest_api and underlying rest to endpoint for clearity
* Rename node/api to node/kernel_api to suggest that it is an internal accessor to node interface + make everything compile after renaming
* make waku api a top level import
* fix use of relative path imports and use default to root rather in case of waku and tools modules
