node: purge dead protobuf tooling — ZAP-native, .proto codegen fully retired

Node has ZERO .proto files and ZERO .pb.go — the wire is hand-written ZAP schemas
(proto/{platformvm,vm,p2p,sync}/*_zap.go). The buf/protoc tooling around it was
orphaned: removed proto/{buf.yaml,buf.gen.yaml,Dockerfile.buf,buf.md,README.md},
scripts/protobuf_codegen.sh, the Taskfile generate-protobuf + check-generate-protobuf
targets, ci.yml buf-lint + check_generated_protobuf jobs (the latter ran the deleted
script → would fail CI), and the buf-lint.yml workflow. defaultPatch 10→11 (dev
version string; image already correct via ldflags). Binary unchanged — tooling/CI only.
