54dd3c864a basic mobs & co no longer indiscriminately perform close-range actions in the presence of obstacles. (#75687)
## About The Pull Request
Currently, we don't have any such thing as a general ai_behavior flag
for behaviors that need a check for if the current_movement_target is
within reach or not. We could fix it case by case by slapping a
`CanReach()` check in the `performBehavior()` definition of every
`ai_behavior` datum that warrants it, the general issue will keep
resurfacing as long as new behaviors are added to the game anyhow, while
there's a lot less copypasta involved easier to apply solution to
current and future instances of such issue.

Worth mentioning not all ai_behaviors with required_range of 1 have this
flag. Some are fairly innocuous, such as the follow command, some others
kind of handle it already in a more peculiar or complex way, which is
also an argument against making it a hardcoded heck for when the
required_range is 1 or 0.

This has been tested, though there are some rough edges and oddities
also unrelated to his PR that might have evaded scrutiny.

## Why It's Good For The Game
This should fix #74823, fix #69254, and fix #74713 (I guess? it could
have been phrased better).

## Changelog

fix: basic mobs & co no longer indiscriminately perform close-range
actions in the presence of obstacles such as directional windows between
them and their target.
fix: Doggos should look at you with longing eyes once again if you dare
pick up an edible they are trying to eat.

ed2f04f486 Experiment with replacing weakrefs in AI blackboard with deleting signals, ideally making it easier to work with and harder to cause hard deletes (#74791)
## About The Pull Request

Replaces weakref usage in AI blackboards with deleting signals

All blackboard var setting must go through setters rather than directly

## Why It's Good For The Game

This both makes it a ton easier to develop AI for, and also makes it
harder for hard deletes to sneak in, as has been seen with recent 515
prs showing hard deletes in AI blackboards

(To quantify "making it easier to develop AI", I found multiple bugs in
existing AI code due to the usage of weakrefs.)

I'm looking for `@Jacquerel` `@tralezab` 's opinions on the matter, also
maybe `@LemonInTheDark` if they're interested

4c48966ff8 Renames delta time to be a more obvious name (#74654)
This tracks the seconds per tick of a subsystem, however note that it is
not completely accurate, as subsystems can be delayed, however it's
useful to have this number as a multiplier or ratio, so that if in
future someone changes the subsystem wait time code correctly adjusts
how fast it applies effects

I broke this in a so-called "refactor" by forgetting to pass an
argument. It works again now.

## Why It's Good For The Game

It's a fun thing for dogs to do.

8dc3fb19f2 Some tweaks to mobs running away (#72529)
## About The Pull Request

Mice running away behaviour wasn't working quite how it was supposed to
due to a couple of bugs.
First of all, the action was written as if it would `perform` every
tick, which it doesn't. This means that the code checking if you had
left line of sight didn't function, meaning mobs would continue fleeing
you even when they couldn't see you any more.

Secondly, mobs spent an awful lot of time pathing into walls which was
especially noticeable on mice who just would _not_ stop repeatedly
squeaking in a way that is kind of funny but gets old when you keep
hearing it. Now the pathing stops if it hits a barrier.
I'm not... totally fond of this solution because it has a few
assumptions baked in (that we want to try and path through doors even if
they're dense for one) but I can't for the moment think of a better
"path away from" implementation that isn't way more complicated, and
this doesn't really need to be complicated.

For good measure I noticed a couple of other actions weren't passing a
`source_atom` into `is_blocked_turf` so rats were potentially attacking
"obstacles" they could simply walk over.
Additionally a couple of places were setting
`controller.movement_target` directly instead of using the helper method
which has a minor risk of runtiming under certain conditions.

## Why It's Good For The Game

Mice will stop constantly screaming if they can see someone, and should
repath once they have a different escape route more quickly rather than
dedicating themselves to trying to burrow through an iron wall.
Rats won't bite at tables and racks they can just climb over.

## Changelog

🆑
fix: Mice won't try to path through walls to escape from sight and
constantly squeak.
fix: Mice will stop running away from you if they can't see you any
more.
fix: Rats won't bite racks and tables while passing over them.

eb6c0eb37c Dogs use the Pet Command system (#72045)
About The Pull Request

Chiefly this refactors dogs to use the newer component/datum system for "pet which follows instructions". It also refactors it a little bit because I had better ideas while working on this than I had last week. Specifically, instead of passing around keys we just stick a weakref to our currently active behaviour in the blackboard. Basically the same but skipping an unecessary step.

Additionally it adds a component for the previous "befriending a mob by clicking it repeatedly" behaviour which hopefully we won't use too much because it's not very exciting (I am planning on replacing it for dogs some time after Christmas).
The biggest effort in here was making the Fetch command more generic, which includes multiple behaviours (which might be used on their own?) and another component (for holding an item without hands).

Additionally I noticed that dogs would keep following my instructions after they died.
This seems unideal, and would be unideal for virtually any AI controller, so I added it as an AI_flag just in case there's some circumstance where you do want to process AI on a dead mob.

Finally this should replicate all behaviour Ian already had plus "follow" (from rats) and a new bonus easter egg reaction, however I noticed that the fetch command is supposed to have Ian eat any food that you try to get him to fetch.
This has been broken for some time and I will be away from my desk for a couple weeks pretty soon, so I wrote the behaviour for this but left it unused. I will come back to this in the future, once I figure out a way to implement it which does not require adding the "you can hit this" flag to every edible item.

Also I had to refit the recent addition of dogs barking at felinids to fit into this, with a side effect that now dogs won't get mad at a Felinid they are friends with. This... feels like intended behaviour anyway?
Why It's Good For The Game

It's good for these to work the same way instead of reimplementing the same behaviour in multiple files.
Being able to have Ian (or other dogs) follow you around the station is both fun and cute, and also makes him significantly more vulnerable to being murdered.
Changelog

add: Ian has learned some new tricks, tell him what a good boy he is!
add: Ian will come on a walk with you, if you are his friend.
refactor: Ian's tricks work the same way as some other mobs' tricks and should be extendable to future mobs.
fix: Dogs no longer run at the maximum possible speed for a mob at all times.
add: When Ian gets old, he also slows down. Poor little guy.
add: Dogs will no longer dislike the presence of Felinids who have taken the time to befriend them.

38bd952b19 Pet Command Component + Regal Rats can order their subjects around (#71590)
## About The Pull Request

Another atomisation of #71421 but I had a fun idea while I was testing
it.

This adds a component based on the existing system for giving
instructions to tamed carp or dogs, but hopefully more modular.
It also gives it to the rat minions of a regal rat.
The basic function allows the mob to listen and react to spoken
commands, which passes things to its AI blackboard. Additionally if you
alt-click a commandable mob it will show a radial menu which both allows
you to select a command, and also contains tooltips explaining what they
do and what audible words trigger it.

</details>

Now if you riot some rats, you can alt click on them individually to
give them specific orders (more useful for other creatures than rats),
or you can speak out loud to command your legion.
Rats aren't very smart so you can't give them many instructions, but
this is expandable for other creatures.

Additional change: Mice don't squeak if stepped on by other mice because
this made an absolutely unholy noise and I am not sure there's a way to
get non-dense mobs to spread out.

## Why It's Good For The Game

Allows for giving more mobs the ability to be tamed and instructable by
their owner, without copy/pasting code which lives inside a specific
mob.
Yelling at your rats to give them commands is funny. It also adds the
possibility of telling your rats to stop biting someone if they have
agreed to your demands, allowing for more courtly roleplay.
When Regal Rat is converted to a basic mob its AI can also give other
AIs instructions by yelling at them which I think is a good feature.

## Changelog

🆑
add: The followers of Regal Rats will now respond to simple
instructions, if given by their rightful lord. Except frogs. They're too
busy licking themselves and watching the colours.
