refactor: use built-in wellformed operation

[climba03003]

From my local benchmark, it vary too large to conclude it has improvement or regression.

The benchmark shows there is a regression on non-affected code routine. For my local environment, it show the similar conclusion but improvement on the string.

Can anyone confirm the same result on node@24? (Github Actions using node@22)

isWellFormed() seem 2X faster, see bench

It should probably also be checked whether the magic numbers 42 and 5000 are still valid string lengths

@cesco69 If you want you can benchmark and provide maybe a PR ;)
