Read the default runtime file policy from a `RuntimeSink` only when it is actually file-backed.
The returned `FileSinkPolicy` value is owned by `src/file_model`; this method belongs to the runtime facade layer and avoids fabricating that model on non-file variants.
This is the truthful companion to `file_default_policy()`. Prefer it when default-policy inspection should not fabricate a fallback object on non-file sinks.

- Plain `File` runtime variants return `Some(default_policy)`.
- `QueuedFile` runtime variants forward the wrapped inner file sink default policy as `Some(default_policy)`.
- The wrapped value is the shared `@file_model.FileSinkPolicy` model, not a runtime-owned concrete type.
- Non-file runtime variants return `None`.
- This helper is useful when callers need to compare runtime drift or restore defaults without fabricating file semantics.
