<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:

windows or doors) could let air leak out into space.

<details open="true"><summary><h1>Original Body</h1></summary>
> <!-- Please read these guidelines before opening your PR:
https://docs.spacestation14.io/en/getting-started/pr-guideline -->
> <!-- The text between the arrows are comments - they will not be
visible on your PR. -->
>
> ## About the PR
> <!-- What did you change in this PR? -->
> Changed almost all[^1] obsolete `Logger` calls in Content's
`EntitySystem`s to use `Log` instead. `Log` automatically selects the
system-specific `Sawmill`, so this isn't just a refactor - it makes logs
slightly more accurate (puts them in appropriate sawmill/context rather
than the root sawmill).
>
> ## Why / Balance
> <!-- Why was it changed? Link any discussions or issues here. Please
discuss how this would affect game balance. -->
> Using `Logger` directly for logging is marked obsolete. Assumed this
is a desired change.
>
> ## Technical details
> <!-- If this is a code change, summarize at high level how your new
code works. This makes it easier to review. -->
> This changes some log contexts, but generally in a desirable way:
> - For most, it put logs in `system.appropriate` `Sawmill` rather than
root.
> - For some that were forced into another `Sawmill` it changes it to a
more specific one, i.e. from `atmos` it becomes `system.gas_filter` or
`system.automatic_atmos` and `system.station` into
`system.station_jobs`.
> - For the rest it remains unchanged
>
> **I assumed that all of the above was desirable because this seems to
be the standard convention** - I imagine that was the idea behind the
`Log` in all `EntitySystem`s coupled with `[Obsolete] Logger` methods -
**but if my assumptions are incorrect and/or there are exceptions,
please let me know and I will adjust.**
>
> [^1]: There is only one `EntitySystem` that I didn't update -
`ExamineSystemShared`. That is because the `Logger` is in a `static`
method and refactoring that away causes a lot of cascading changes. May
do it as a separate PR to avoid overly diluting this one.
