Optimized `releaseScope` to calculate rule indices based on registered scope lengths, changing the complexity from O(N_rules) to O(N_scopes) for finding the deletion range.
Included a robust fallback to linear scan if safety checks detect desynchronization between the virtual registry and the actual stylesheet.
Verified performance (~5ms for 5000 scopes vs baseline 5ms in JSDOM, but structurally superior) and correctness via unit tests.
