--- Allows bots to hold shared state on the bot context. Commands would be able to access this state within their `execute` handlers as `ctx.shared_state`. This would provide SDK support for shared state, though making the type signatures somewhat more complex.

If we have to pass in the shared state every time that would look messy for the majority of use cases where the shared state will be ().
So maybe we instead hold the shared state in the CommandHandlerRegistry?
Then it automatically passes it through to command_handler.execute.
Or are you envisioning potentially passing in different instances, but the type always remains the same?

If we were to hold the state on the CommandHandlerRegistry then we could set a default for S as S = (), and then expose a with_shared_state which would hand the value to CommandHandlerRegistry and also set the S generic type on the returned instance.

Commands would be able to access this state within their
executehandlers asctx.shared_state. Command definition structs would only need to reference local state.This would provide SDK support for shared state, though making the type signatures somewhat more complex. For not shared state we'd use unit type
().(breaking change)
