Fix: Panic when path limit exceeded (main)

The stats module now panics when the path limit is
exceeded instead of using an overflow bucket. This
change improves error handling and provides more
actionable feedback to the user.  It also simplifies
the code by removing the overflow logic.  If you
encounter this panic, please open an issue on GitHub
or raise the `stats.maxPaths` constant.
