[minor] iflimit regression

[dginev]

Now that a texlive 2025 make formats succeeds with a full load, I started seeing the Dockerized config we use for arXiv fail with a strange "instant Fatal" due to iflimit being exceeded.

Then I looked at the format file and saw:

V('if_count',4154919);

That number has to be 0 at the start of a fresh latexml conversion run, so it is problematic that it got cached during the formats step. Several patch approaches came to mind, but the one that I believe is "Correct" is:

Avoid using the if_count state value in any situation where the IF_LIMIT isn't set. That way make formats never sets it, and we resume with the clean slate from before.

[aside] We have now learned that the texlive 2025 latex 3 kernel used 4.1 million conditionals in building.

[background] To use the conditional limit, our config sets

--preload=[iflimit=3999999]latexml.sty

But if_count is useful for debugging & tracing as well, so disabling it is not so good.

Changed to the discussed strategy of simply omitting these value keys from the precompiled kernel Dump call. A local make format seems to work.

The Dumper file had large changes when latexmllint ran over it -- hope those are OK.

looks good; thanks!
