Minor Changes

• #1350 3a1140f Thanks @threepointone! - Align Think generics with Agent / AIChatAgent.

  Think is now Think<Env, State, Props> and extends Agent<Env, State, Props>, so subclasses get properly typed this.state, this.setState(), initialState, and this.ctx.props. The previous Config class generic is removed.

  configure() and getConfig() remain, but the config type is now specified at the call site via a method-level generic:

  // Before
  export class MyAgent extends Think<Env, MyConfig> {
    getModel() {
      const tier = this.getConfig()?.modelTier ?? "fast";
      // ...
    }
  }
  
  // After
  export class MyAgent extends Think<Env> {
    getModel() {
      const tier = this.getConfig<MyConfig>()?.modelTier ?? "fast";
      // ...
    }
  }

  This is a breaking change for anyone using the second type parameter of Think. Update the class declaration and any direct configure(...) / getConfig() call sites that relied on the class-level Config type.
