// build.rs — compile the trimmed `proto/dwarf.proto` into a prost+tonic CLIENT.
//
// Pure-Rust codegen (the nordisk zero-shell charter): `protox` (a pure-Rust .proto
// parser) produces the FileDescriptorSet, then `tonic-build` emits the client
// bindings from it — no `protoc` binary, no C. Mirrors `nornir-funnel-embed/build.rs`.
