Projection Determinism: JCS helper/harness #54
Description
Title
Projection Determinism: JCS helper/harness
Goal
Add a minimal JCS harness (or dependency guidance) for generating canonical bytes in tests and tools.
Acceptance Criteria
- Helper function or script to produce RFC 8785 canonical bytes from JSON.
- Used by determinism tests and by any CLI tools that compute content_id.
- Documentation snippet on when/how to use.
Notes
- Can be a tiny script or a recommended dependency with a stable version pin.
