Fixed in commit fix: update severity field access for oxc-miette v3 API change.

In oxc-miette v3, severity changed from a trait method returning Option<Severity> to a direct struct field of type Severity on OxcDiagnosticInner. The default value is Severity::Error, so the old is_none() guard (which treated diagnostics with no severity as errors) is now handled implicitly by the field's default — behavior is preserved.
