GhomandShadow-Quill 11d82b7995 You can now interact with held mobs beside wearing them (feat: "minor" melee attack chain cleanup) (#90080)
People can now pet held mothroaches and pugs if they want to, or use
items on them, hopefully without causing many issues. After all, it only
took about a couple dozen lines of code to make...

...Oh, did the 527 files changed or the 850~ lines added/removed perhaps
catch your eye? Made you wonder if I accidentally pushed the wrong
branch? or skewed something up big time? Well, nuh uh. I just happen to
be fed up with the melee attack chain still using stringized params
instead of an array/list. It was frankly revolting to see how I'd have
had to otherwise call `list2params` for what I'm trying to accomplish
here, and make this PR another tessera to the immense stupidity of our
attack chain procs calling `params2list` over and over and over instead
of just using that one call instance from `ClickOn` as an argument. It's
2025, honey, wake up!

I also tried to replace some of those single letter vars/args but there
are just way too many of them.

Improving old code. And I want to be able to pet mobroaches while
holding them too.

🆑
qol: You can now interact with held mobs in more ways beside wearing
them.
