DGR-023: Make Python and C++ protobuf generation reproducible

Status / triage: completed; passes: true
Execution mode: AFK
Milestone: M1
Dependencies: DGR-021
Blocks (derived): DGR-024, DGR-037
Labels: area:protocol, area:build, type:tooling, priority:p0, ready-for-agent
Evidence class: model-free
Hardware: none
Model: generic
Upstream: no

Objective / description

Fresh Ralph session: read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md, source issue .scratch/distributed-gguf-runtime/issues/023-make-python-and-c-protobuf-generation-reproducible.md, and evidence READMEs for dependencies (DGR-021) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Generate identical Python/C++ protocol bindings without manual copying or checked-in build debris.

Acceptance criteria

Pin protoc, gRPC, and plugin versions or declare a verified compatible range.
Generate Python and C++ bindings into out-of-tree build/package locations through documented commands.
Add Python↔C++ round-trip and descriptor compatibility tests.
A clean checkout regenerates bindings deterministically or fails with an actionable toolchain error.
Applicable shared quality gates in prd.json pass, and the evidence handoff records exact commands/results, changed files, limitations, and dependency handoff.

Shared quality gates

Targeted deterministic tests pass; Python changes also pass python -m compileall packages tests.
git diff --check passes.
Default tests are model-download-free, API-credit-free, and GPU-free.
Evidence README records exact changed files, commands/results, limitations, and dependency handoff; no fabricated evidence or inherited completion credit.

Evidence handoff

Verified evidence: .scratch/distributed-gguf-runtime/evidence/DGR-023/README.md. Legacy evidence remains provenance only and grants no implementation completion credit.
