feat(common): expose regionDurable over gRPC

TaskDef is a @ProtoMessage and every other field is proto-mapped, so without an
id the flag could not travel over gRPC — a client setting it would silently get
the default. Annotate it (id 26, the next free one) and commit the protogen
output: the field in taskdef.proto and the two AbstractProtoMapper lines.
