Function contract_id_to_service_name 

pub fn contract_id_to_service_name(id: &str) -> String

Mirrors robonix_codegen::contract_gen::contract_id_to_service_name. Uniform PascalCase: robonix/primitive/chassis/driver → RobonixPrimitiveChassisDriver. No prefix stripping. Full gRPC service path: /robonix.contracts.<this>/Driver.

Lifted out of cmd::deploy so Soma can build the same gRPC URLs without re-implementing the rule (which would drift).
