Pull request overview

This PR fixes a critical memory leak bug in the useNow hook. The hook manages a shared timestamp that updates every second using a reference counter to track how many components are using it. The original implementation failed to decrement the counter during cleanup, preventing the timer from ever being cleared once multiple components had mounted, causing a resource leak.

Changes:

• Fixed the cleanup function to properly decrement the reference counter before checking if cleanup should proceed
• Changed the condition from checking counter > 1 to decrementing first then checking counter > 0
