The nil check burn down added guards which turned out redundant once
the surrounding annotations landed. `_has_handlers` is set to true when
the first handler registers, so it is a boolean rather than the literal
false it was inferred as.

`assert` returns every argument it is given, so `return assert(x, msg)`
was leaking the message as a second return value.
`get_tile` is documented as taking x and y. The async function class
declared `@operator call` with no parameters, which made every async
call look over supplied.

The top, left and relative element tables are keyed by the define, but
the duplicate registration assert looked up `define.name`, so it never
fired.
GuiIter.remove_element indexed `registered_scopes` by player index
instead of the scope elements it had just fetched, so it removed
nothing.

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.

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`.
