Fix self-referencing imports for namespaced serializers

[chris-mangrove]

Summary

• Fixes incorrect self-reference detection for namespaced serializers
• Prevents TypeScript error TS2440 (module imports itself)

Problem

When a namespaced serializer (e.g., Inventory::ItemSerializer) has a self-referential association (like a tree structure with parent/children), the generated TypeScript file incorrectly imported itself:

// Generated with bug - imports itself!
import { InventoryItem } from './InventoryItem';

export interface InventoryItem {
  id: number;
  parent: InventoryItem;
  children: InventoryItem[];
}

This caused TypeScript error TS2440: "Import declaration conflicts with local declaration."

Root Cause

The self_type_name method used a regex that only captured the last segment of the serializer name:

serializer.name.match(/(\w+::)?(\w+)(Serializer|Resource)/)[2]
# Returns "Item" for "Inventory::ItemSerializer"

But the actual generated type name joins all namespace segments: InventoryItem. This mismatch caused self-references to slip through the import filter.

Solution

Use the name method which already returns the correctly formatted type name, ensuring self-references are properly excluded from imports.

Hey @chris-mangrove, could you provide a serializer example? I can't repro the issue

[skryukov]

Ok, my guess is that you are calling typelize parent: 'InventoryItem', if so, the fix is here: #74

Awesome - thank you @skryukov; #74 did fix my issue.
