Module trigger 

trigger

Purpose:

• Define kernel trigger primitive types, manifests, validation errors, and registry helpers.

Owns:

• TriggerValidationError as the typed registration failure surface for trigger primitives.
• Trigger type metadata and registry-facing trigger declarations.

Does not own:

• Catalog-level wrapper errors or host-facing rendering.
• Trigger execution orchestration outside kernel registration.

Connects to:

• catalog.rs, which wraps trigger registration failures.
• Trigger implementations under implementations/.

Safety notes:

• Display stays aligned with ErrorInfo so trigger registration meaning is not duplicated across layers.
