Replace codec.Uint64/Float64 with in-package Uint64/Float64 JSON wrappers (jsonnum.go). The pubsub messages need string-encoded numerics at the JSON-RPC boundary; no broader codec dependency is needed for that. Files touched: - jsonnum.go (new): Uint64/Float64 with MarshalJSON/UnmarshalJSON - messages.go: drop codec import, use local Uint64/Float64 luxfi/codec is now indirect-only via workspace transitives.
