PSRPC for Hanzo LiveKit, forked from livekit/psrpc (Apache-2.0). Two rewrites: github.com/livekit/psrpc -> github.com/hanzoai/psrpc github.com/redis/go-redis/v9 -> github.com/hanzokv/go/v9 psrpc's message bus (bus.go, internal/bus/bus_redis.go, internal/bus/bustest) speaks to a KV over go-redis. After hanzoai/livekit moved to our client, psrpc was the one remaining edge pulling upstream go-redis into that binary — not our code, but our dependency, the same shape redsync had for hanzoai/git. The other livekit/* modules (protocol, mediatransportutil, mageutil) are NOT forked and should not be: none of them touch a KV client, so they are ordinary external dependencies and their names are addresses.
