Function useDeepCommandState

useDeepCommandState<T>(
    initial: T,
    handlers: { [action: string]: (state: T, cmd: Command) => T },
    options?: UseCommandStateOptions,
): { state: Signal<T>; dispose: () => void }
useDeepCommandState — useCommandState with deep (Proxy-backed) reactivity.

Identical dispatch/coalesce/cleanup semantics to useCommandState; the only difference is the returned state is a deep ref(), so BOTH command-driven whole-value replacement AND direct nested mutation (state.value.a.b = c) trigger reactivity. Use it for hybrid models that mix command dispatch with two-way bound fields. For pure command-driven state, prefer the faster useCommandState from the core.
Type Parameters
- T
Parameters
- initial: T
- handlers: { [action: string]: (state: T, cmd: Command) => T }
- options: UseCommandStateOptions = {}
Returns { state: Signal<T>; dispose: () => void }
Example
```
const { state, dispose } = useDeepCommandState(
  { items: [] as number[] },
  { add: (s, cmd) => ({ ...s, items: [...s.items, cmd.target as number] }) },
  { coalesce: true },
);
```
