Waterpig 08d9f59838 [NO GBP] Slime AI fixes + prerequisites (newest mirror: makes slimes not idle) (#27470)
* Reworks targeting behavior to fall back onto proximity monitors. Refactors ai cooldowns a bit (#82640)

## About The Pull Request

Nother bit ripped out of #79498
[Implements a get_cooldown() proc to get around dumb manual overrides
and empower me to optimize the findtarget
logic](7047d294dd)

[Adds modify_cooldown, uses it to optimize find_potential_targets
further](4ebc8cedce)

No sense running the behavior if we're just waiting on its output, so
let's run it once a minute just in case, then push an update instantly
if we find something

[Optimizes connect_range and
promxity_monitors](bcf7d7c5b3)

We know what turfs exist before and after a move
We can use this information to prevent trying to update turfs we don't
care about.

This is important because post these changes mobs with fields will be
moving a lot more, so it's gotta be cheap

[Implements a special kind of field to handle ai
targeting](80b63b3445)

If we run targeting and don't like, find anything, we should setup a
field that listens for things coming near us and then handle those
things as we find them.

This incurs a slight startup cost but saves so much time on the churn of
constant costs

Note:
We should also work to figure out a way to avoid waking ais if none is
near them/they aren't doing anything interesting

We don't need to do that immediately this acts as somewhat of a stopgap
(and would be good regardless) but it is worth keeping in mind)

## IMPORTANT

I am unsure whether this is worth it anymore since #82539 was merged. As
I say it was done as a stopgap because ais didn't know how to idle.
If not I'll rip er out and we'll keep the other
refactoring/optimizations.

## Why It's Good For The Game

Cleaner basic ai code, maybe? faster basic ai code, for sure faster
proximity monitors (significantly)

* ai controllers use cell trackers to know when to idle (#82691)

## About The Pull Request
this makes ai controllers use cell trackers and signals to determine
when to idle

## Why It's Good For The Game
might be better than looping over all clients for every controller

## Changelog
🆑
code: The way mobs idle has been refactored, please report any issues
with non-reactive mobs
/🆑

* makes slimes not idle (#82742)

## About The Pull Request
slimes should still be able to do their everyday routine without needing
to be watched over

## Why It's Good For The Game
makes xenobiologist's lives easier

## Changelog
🆑
qol: slimes will stay active without needing any one to watch over
/🆑
