relayer: update client bindings to 0xsequence/relayer@0b3c169

[marino39]

Summary

• Regenerate relayer/proto/relayer.gen.go and lib/mock/relayer.mock.go from 0xsequence/relayer@master (commit 0b3c169).
• Upstream changed GetMetaTxnReceipt to return (*MetaTxnReceipt, bool, error) — the new bool is metaTxnEnqueued. Discard the bool in relayer/relayer.go to preserve current wait-loop behavior.
• No new wrapper helpers; new upstream RPCs remain reachable via the embedded proto.RelayerClient.

Test Plan

• go build ./... passes
• go vet ./... clean (pre-existing lib/compressor/cbuffer.go warning unrelated)
• go test ./relayer/... ./lib/mock/... passes
• go generate ./lib/mock is idempotent
• var _ sequence.Relayer = &Client{} static assertion still compiles

Follow-up

metaTxnEnqueued is currently discarded at relayer/relayer.go:387. The existing "this is a hack, we should use proper error codes when we upgrade webrpc version" comment can now be addressed by using the new flag — left for a separate change to keep this bump behavior-neutral.
