Provides safe, controlled access to fiber-level operations and metadata.
This hook MUST be called at the top level of a component function — never inside loops, conditions, nested functions, or callbacks.
The call order of all hooks is strictly fixed across every refresh; reordering calls will corrupt internal state.
Returned object is stable across refreshes.
Use this instead of useFiber() when you need fiber introspection or manual control.
