fix: properly handle cyclic objects

[dannote]

I encountered the following error when logging objects with circular references:

[Error] <RouterView> @ component update – TypeError: JSON.stringify cannot serialize cyclic structures. — @hawk__so_javascript.js:766

This error occurs because JSON.stringify cannot handle cyclic structures, causing the application to crash when such objects are logged.

To address this, my PR introduces the safeStringify function from the safe-stringify package (new dependency added). This utility safely serializes objects, replacing circular references with a [Circular] marker.
