* bump nim-libp2p pin to v2.0.0 tag * bump json_rpc to v0.6.1, lsquic to v0.5.1, boringssl to v0.0.8 (latest tags) * add libp2p_mix dep; repoint libp2p/protocols/mix -> libp2p_mix * pin nimble.lock: websock / protobuf_serialization / npeg / jwt * Makefile: add -d:libp2p_quic_support * regenerate nix/deps.nix (adds libp2p_mix, refreshes pins) * migrate rng ref HmacDrbgContext -> libp2p Rng across prod/channels/tests (interface-only; same DRBG) * waku_switch: TransportConfig factory; unified 2.0.0 connection limits (withMaxInOut, withMaxConnections); local MaxConnections * waku_relay/rendezvous/discv5/kademlia: v2.0.0 API (rng, config, ServiceDiscovery rename) * call Service.setup() on post-build switch services (2.0.0 split setup/start) * drop libp2p/utils/semaphore -> chronos AsyncSemaphore * add logos_delivery/waku/compat/option_valueor shim (Option[T] valueOr/withValue, dropped upstream) * add std/options where a transitive re-export was removed * add newStandardSwitch shim (libp2p removed it in 2.0.0); mounts yamux+mplex to match prod muxer * PeerId.random(rng); common.rng()/crypto.newRng(); hoist shared rng (instantiation cleanup) * update expectations for 2.0.0 defaults: DEFAULT_PROTOCOLS += /ipfs/id/push/1.0.0; agent "nim-libp2p" * drop relay reboot/reconnect test (asserted a Switch restart capability that is simply not supported) * fix up a few tests that were flaking on MacOS (libp2p upgrade may have exposed these)
