Code generation policy

Decision: - Do not commit generated protobuf outputs (e.g., core/src-gen). - Generated code is produced during Docker build (and optionally in CI).

Rationale

Avoids noisy diffs and merge conflicts.
Ensures generation is reproducible from pinned toolchains.
Keeps the repo focused on source-of-truth (.proto).

How it works

core/Dockerfile installs and pins:
- buf
- protoc
- proto-lens-protoc
During image build, protobuf modules are generated into core/src-gen/.

Local development

If you want to generate locally:

bash scripts/proto-generate.sh
