<details open="true"><summary><h1>Original Body</h1></summary>
> This PR reworks how some parts of atmos code work. Originally it was
just meant to be a performance and bugfix PR, but it has ballooned in
scope. I'm not sure about some of my changes largely because I'm not
sure if some things were an oversight or an intentional decision for
some reason.
>
> List of changes:
> - The `MolesArchived float[]` field is now read-only
> - It simply gets zeroed whenever the `GasMixture` is set to null
instead of constantly reallocating
> - Airtight query information is now cached in `TileAtmosphere`
> - This means that it should only iterate over anchored entities once
per update.
> - Previously an invalidated atmos tile would cause
`ProcessRevalidate()` to query airtight entities on the same tile six
times by calling a combination of `GridIsTileAirBlocked()`,
`NeedsVacuumFixing()`, and `GridIsTileAirBlocked()`. So this should help
significantly reduce component lookups & entity enumeration.
> - This does change some behaviour. In particular blocked directions
are now only updated if the tile was invalidated prior to the current
atmos-update, and will only ever be updated once per atmos-update.
> - AFAIK this only has an effect if the invalid tile processing is
deferred over multiple ticks, and I don't think it should cause any
issues?
> - Fixes a potential bug, where tiles might not dispose of their
excited group if their direction flags changed.
> - `MapAtmosphereComponent.Mixture` is now always immutable and no
longer nullable
> - I'm not sure why the mixture was nullable before? AFAICT the
component is meaningless if its null?
> - Space "gas" was always immutable, but there was nothing that
required planet atmospheres to be immutable. Requiring that it be
immutable gets rid of the constant gas mixture cloning.
> - I don't know if there was a reason for why they weren't immutable to
begin with.
> - Fixes lungs removing too much air from a gas mixture, resulting in
negative moles.
> - `GasMixture.Moles` is now `[Access]` restricted to the atmosphere
system.
> - This is to prevent people from improperly modifying the gas mixtures
(e.g., lungs), or accidentally modifying immutable mixtures.
> - Fixes an issue where non-grid atmosphere tiles would fail to update
their adjacent tiles, resulting in null reference exception spam
> - Fixes#21732
> - Fixes#21210 (probably)
> - Disconnected atmosphere tiles, i.e., tiles that aren't on or
adjacent to a grid tile, will now get removed from the tile set.
Previously the tile set would just always increase, with tiles never
getting removed.
> - Removes various redundant component and tile-definition queries.
> - Removes some method events in favour of just using methods.
> - Map-exposded tiles now get updated when a map's atmosphere changes
(or the grid moves across maps).
> - Adds a `setmapatmos` command for adding map-wide atmospheres.
> - Fixed (non-planet) map atmospheres rendering over grids.
>
> ## Media
>
> This PR also includes changes to the atmos debug overlay, though I've
also split that off into a separate PR to make reviewing easier
(#22520).

> Below is a video showing that atmos still seems to work, and that
trimming of disconnected tiles works:

* AutoCompState + ItemToggle fixes
Fix a lot of the comp states that are never actually networked and also cleaned up ItemToggle events a bunch. ItemToggle will still need some future work for lights and sounds.
* Also catch these
(cherry picked from commit 2166958bd0c23b7b9fd5c699eaeee910d1db62bf)
* Add some tests and fix some bugs
* Add more helper methods
* remove submodule
* fix merge
* also fix DirtyAll()
* poke
(cherry picked from commit 35ba42af9ccbbe41e8a3e59b30f2799ef8ca4b8d)
* Fixed EnergySword and variants having incorrect sound on attacking when in their Off state.
* Removed the unused ItemToggle from the serverside and created a new shared ItemToggleComponent and System, now used for the e-blade family of items. Also added e-blade hum and swing sounds. Thanks Sloth for the initial code!
* Changing Stunbaton system to include the itemToggle system.
* Adapted changes that have come up in the meantime.
* Changed damagespecifier to be serializable and autoNetworked in melee weapon components. Fixes a bug that makes it so client-side, damage values are not updated on toggle.
* Made the ItemToggleSystem have both a shared and a server component. Ported the Stun Baton and Stun Prod to the new toggleable system. Added a failure to activate noise component.
* Ported the welders to the new item toggle system. Set it so deactivated damage and item size default to the item's regular options.
* Removed unnecessary usings.
* Small modification to the stun prod.
* Made the integration test use the new method to turn the welders on.
* Fixed a few testing issues, applied a few changes requested by Delta.
* Updated Stunbaton code for consistentcy when it comes to calling the itemToggle component.
* Removed a redundant return; as per Delta.
Made examining the stun baton for charge rely on the battery component instead.
* Removed the welder visualizer system, now using the generic one. Removed some unused usings. Removed the welder visuals and layers.
Ported lighters to the new system.
Added zippi (sic) lighters.
* Renamed variables used to make them less generic.
* Simplified the light update code.
* Fixed the unit test to use the itemToggle system for welders now.
* Made the name shorter. I can't tell if the welding damage when interacted with actually does anything though. I can't figure out how to trigger it.
* Fixed some YML issues.
* Added a client side item toggle system just to make the shared code run on local UID's too.
* Fixed some more Yaml.
* Made the Zippi lighter have its own parent item, so it doesnt' conflict with the random pattern on the regular lighter.
* Made the zippi lighter its own in-hand sprites.
* Added a summary for the activated property in itemtoggle component.
* Fixed a typo in the itemToggle Component.
* Fixed a typo.
* Added to the remarks for the ItemToggleComponent.
* Fixed up the lighter yaml to make it use a generic term instead of a toggle layer enum for the random skin.
* Fixed a bug I introduced accidentally with the humming sound.
* Removed 2 unnecessary events from the ItemToggleSystem and component.
* Fixed a bug by only making the server run the item activation code, since the client cannot predict whether or not the activation will be cancelled.
* Cleaned up some names and functions getting called.
* Renamed a couple of variables and removed the explicit datafields from the component. Removed "activated: false" from yml since they're already deactivated by default.
* Added an IsActivated function, used it in the welder and stun baton systems code.
Refactored welder code to remove the WelderToggle event, now using the ItemToggleActivatedEvent instead for eye protection check.
* Fixed a typo. Added some comments.
* Split the ItemToggle into smaller components.
Changed the items that used the toggle system to work with the smaller components.
Made the mirror shield reflect energy shots with a 95% chance.
* Fixed the namespaces for the server components and whatnot.
* Fixed a doubled deactivation sound from using activated wieldable items (like the double Esword).
Fixed wrong yml with the e-dagger.
Fixed the disarm malus code.
* Added the zippo lighter to the detective's trench coat.
* Removed the default hit sound for the double e-sword since it was unnecessary.
* Changed e-sword damage numbers to be in line with the changes made by Emisse.
* Made no damage sounds be autoNetworked, so it changes can be changed on activation/deactivation of items.
Made Welders and Eswords sound like themselves but quieter if they hit for 0 damage, instead of taps.
You can choose what sound to play when a weapon does 0 damage when activated now.
Fixed a bug with swing sounds.
* Typo.
* Fixed a bug where the welder would blind you if you used it while it was off.
* Created a single abstract method called when an item has completed its toggle.
* Update Content.Server/Eye/Blinding/EyeProtection/EyeProtectionSystem.cs

* Removed trailing white spaces.
* Made the Use a field instead of a property in the itemToggleActivation/Deactivation attempt events.
* Small fixes.
