Add opt-in protomux-rpc GUILD_SYNC_REQUEST pull when PEARCORD_RPC_WIRE=v2|dual
and PEARCORD_RPC_REQUEST_WIRE=1. Platform binds RPC responders on the mesh host,
joiner uses _tryGuildSyncRequestRpc with event-fanout fallback unchanged by default.
Includes mux-wire/gossip-request.js, live smoke, CI bundle test:ci-phase869, and
hardened dual-stack/v2 roundtrip smokes (bounded flush, longer timeouts). No
breaking change: default gossip event paths remain v1 unless env enables v2.
Queue member join and sync-request gossip through the outbox, infer members from mesh peers and profiles, add host-initiated identify handshake, and harden partition heal plus mesh bounded clearing.

Move 136 prototype mixins under mixins/domain, json-export, and
runtime/* so the package root stays navigable. Manifest assign order
is unchanged; apply-platform-mixins and runtime registry paths updated.
