Old

• Single-pass approach: If a type depended on another type not yet processed, it was left unresolved.
• Relied on order: Some types were skipped because they weren’t recognized in time.
• Nested generics (like some Option) often stayed unresolved because of this.
• Incomplete arrays/sequences: Definitions weren’t fully expanded.

New

• Two-pass resolution: First map simple types; then iteratively resolve nested/complex ones.
• Iterative handling: Re-check pending types until none remain, ensuring dependencies get picked up.
• All generics resolved: Options and similar now properly map their inner types.
