React useLocalStorage Hook Fixes SSR and Tab Sync Bugs

A new useLocalStorage hook from @reactuses/core provides SSR-safe persistent state that survives reloads, serializes non-string data, and syncs across tabs and components. It avoids common bugs in manual useState+useEffect implementations, such as crashes on the server and corrupted data. The hook mirrors useState's API, making it a drop-in replacement for ephemeral state.
