spawn_area accepts both position forms on purpose, so it asserts that
one of the two is present rather than narrowing the type.

Color.struct leaves every channel optional, so the rainbow command
declares its own fully populated colour.

Values read back from the game always use the named members, so they
are narrowed once where they enter a function rather than at each use.
`LuaControl.force` is a ForceID union, so reading a force only method
off it needs the cast the rest of the repo already uses.

`Roles.new_role` returned the result of `error`, which made it nullable,
and `set_permission_group` returned nil for an unknown group, which
broke the config chain with an index error rather than saying so.
Positions and bounding boxes read back from the game always use the
named members, so they are narrowed once where they enter a function.

Locals declared ahead of an assignment inside a callback were inferred
as nil at every use site.
The role event handlers are given a class so the table is not unified
with the other module handler tables.

`LogisticFilter.signal` became `value` in 2.0, so the clear loop broke
on the first slot and outdated signals were left behind.

`_display_data` is a cache keyed by force name, not a single record.
The auto complete accumulator starts empty, so its fields are optional.
Game commands have no usage beyond their own help text.

emmylua only parses the inline cast as `--[[@as T]]`, the spaced form
`--[[ @as T ]]` is treated as a plain comment, so all 149 of them were
doing nothing.
LuaGuiElement.style is a union because a style name can be assigned to
it, so reading it back needs the cast.

emmylua deserialises an unknown diagnostic code to a catch all that
matches no checker, so every `invisible`, `nil-check` and
`global-element` suppression was silently doing nothing. Renamed to the
emmylua codes. `name-style-check` has no equivalent and is dropped, it
was already disabled under luals.
The `get_tile` suppressions referenced an api typedef bug from 2024
which no longer reproduces.
need-check-nil is deferred rather than disabled on merit: a third of the
407 findings come from MapPosition and BoundingBox being aliased as
`struct|[double, double]`, so every `entity.position.x` reads as
possibly nil. The rest need per site knowledge of runtime invariants.

The aabb functions all index the named members, so passing the
shorthand [MapPosition, MapPosition] form would error at runtime. The
annotations now say so.
emmylua requires a type argument on a generic alias, luals did not.

Classes contributed to by more than one file now carry the `partial`
attribute. trains.lua declared its command as `ExpCommand_Artillery`,
which was a copy paste.
`Color.0` and `MapPosition.0` became `.struct` in fmtk 2.1.6.
emmylua rejects `@type` on a function statement or a `do` block, so
those are moved onto the local or replaced by `@param` and `@return`.
