DbtSource does not support setting detected_unsafe

Error message

DbtSource does not support setting detected_unsafe

What it means

DbtSource's set_detected_introspection is an intentional hard panic: sources are external tables defined in YAML; there is no compiled/introspectable state to mark as detected-unsafe, so the trait method is unimplemented for this node kind.

Solutions

1. Filter to model-like nodes before invoking the introspection setter
2. Restrict the call site to node kinds that actually compile against the warehouse
3. Return a benign no-op for sources if the API must stay uniform

When it happens

Trigger: Thrown at crates/dbt-schemas/src/schemas/nodes.rs:2513 when the library encounters an invalid state.
