`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.

Guards now cover the statements that follow them, and a couple of reads
are restructured so the narrowing survives.

get_player_roles always returns at least the default or root role, so
get_player_highest_role never returns nil, and callers were right to
treat it that way.

`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.

`loadstring` was removed in Lua 5.2, `load` takes a string the same way.
Warp gui child lookups are optional, so they use the same assert the
rest of the repo does.

emmylua takes self from the owner table, so `@param self ExpRoles.Role`
only applies with dot syntax. Call sites still use a colon.

`config.temp_warning_limit` does not exist, the warnings config defines
`script_warning_limit`, and the locale expects it as `__3__/__4__`, so
the command was printing nil.
map_tags is keyed by the force name joined to the tag number, and
custom_color is the Color union.

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.

`get_contents` and `targeted_items_pickup`/`_deliver` return lists of
ItemWithQualityCount in 2.0, they are no longer name keyed dictionaries,
so the logistorage stats were indexing by array position.
PreferenceEnum is bidirectional, matching what ExpUtil.enum returns.

The registry and the prototype were both bare tables, so every
`datastore:method()` call resolved to nothing.
