Create Agnostic Composable

Agnostic composables are reusable functions that can accept both reactive and non-reactive inputs. This allows developers to use the composable in a variety of contexts without worrying about the reactivity of the inputs.

Steps to design an agnostic composable in Vue.js:

1. Confirm the composable's purpose and API design and expected inputs/outputs.
2. Identify inputs params that should be reactive (MaybeRef / MaybeRefOrGetter).
3. Use toValue() or toRef() to normalize inputs inside reactive effects.
4. Implement the core logic of the composable using Vue's reactivity APIs.

export type MaybeRef<T = any> = T | Ref<T> | ShallowRef<T> | WritableComputedRef<T>;
