Thank you for merging the new mpn-based factoring code!

The code looks good, I did not see anything which needs improvements.

I believe the factoring speedup for numbers of 3 or more limb is quite
significant (2x-3x), even when not considering the time saved by not
proving primality of found factors.

You might want mention that in the header about the 2025 improvements.
