Type checking for Cell: Allow setters with different Cell<> structure

[seefeldb]

Allow inputs to writing cell methods to have a different Cell<> structure than the destination cell

[Copilot]

Pull Request Overview

This pull request introduces improved type checking for Cell methods by allowing setters to accept a flexible Cell<> structure. Key changes include updating the Cell interface methods (set, send, update, push) to use the new Cellify type transformation, modifying test schemas to use "as const satisfies JSONSchema" for stricter type inference, and updating the builder types to use unique symbols for ID constants.

• [nitpick] The push method union type now wraps array items with Cellify, which might allow inconsistent types; verify that both raw and cellified items are correctly handled as intended.

• Changing ID from a regular symbol to a unique symbol may affect compatibility with external modules; please confirm that all consumers of this constant can work with the new type.

export const ID: unique symbol = Symbol("ID, unique to the context");
