Describe the solution you'd like

Add schema-based support to unsigned number fields for JavaScript:

import { Fory, Type } from '@anthropic/fory';

const fory = new Fory();

// Define type with field metadata
fory.registerType({
  name: 'Foo',
  fields: {
    f1: { type: Type.uint32, id: 0 },
    f3: { type: Type.tagged_int32, id: 2 }
  },
});

Hi @theharsh999 , are you interested in this issue?

Hey @chaokunyang I would like to take this up!

[theharsh999]

Yes, I’m interested. I can work on the JavaScript schema-based support for unsigned numbers and add tests. I may ask questions along the way to align with existing design.

Hi @theharsh999 , would you like to work on Dart unsigned int support first? You can find more details in #3131

Thanks for the update! Since a PR (#3131) is already in progress for this issue, I’ll step back. Happy to help review or take another issue if needed.
