[Bug]: issue creating Arrays using TypeKit

### Describe the bug

See this discussion: https://discord.com/channels/1247582902930116749/1375144881739272272

According to the discussion:
- `array.create(type) === array.create(type);` ought to yield true, but always yields false
- creating arrays using `${context.program}.array.create(type);` yields an array instance without NameSpace and using these as type on ModelProperties will result in errors when emitting OAS or JSONSchema, due to duplicate names (likely icw @visibility options?)
