Describe the feature you'd like to request

Currently TRPC Proxy Client context is of type ClientContext and is not an extendable interface like OperationContext.

Describe the solution you'd like to see

Can TRPC Proxy client's context follow OperationContext? Or make it an interface so we can extend on it.

Describe alternate solutions

I am not sure why Proxy Client did not use OperationContext but the terminating link is using it. Would be good if both types are synced.

Additional information

type ClientContext = Record<string, unknown>;

/**
 * @internal
 */
export interface ProcedureOptions {
  /**
   * Client-side context
   */
  context?: ClientContext;
  signal?: AbortSignal;
}
