Module content_type 

Content type enum and format resolution. Content type enum and format resolution.

Defines the unified content type for all interfaces. Lives in yeti-types (L0) so Context can reference it directly. Serialization implementations that need heavy deps (ciborium, rmp-serde, serde_yaml) live in yeti-sdk (L2).

Resolution priority:

1. Transport headers (Upgrade, Accept: text/event-stream, Content-Type: application/grpc)
2. URL extension (.json, .yaml, .sse, .proto, etc.)
3. ?format= query parameter
4. ?stream=sse query parameter
5. Accept header (standard content negotiation)
6. Default: JSON
