AsyncCondition

@ng-forge/dynamic-forms

Condition that evaluates based on a registered async function.

The function is resolved reactively — when dependent form values change, the function is re-evaluated (with debouncing). The result is cached per evaluation to avoid redundant calls.

Since LogicFn must return boolean synchronously, this condition uses a signal-based async resolution pattern internally.
