A file or library saved before "modes" was an override group has a mode
chosen on a layer inside an instance without its marker, so the next
rebuild or library import still put the main's mode back.
Copies follow their main layer's modes when the main changes them, so a
layer inside an instance on other modes chose them itself.
mark_layer_modes marks those when a file opens and when a published
library is read from a file or a server. Layers on their main's modes
and top-level instances stay unmarked.
A variable mode chosen on a layer inside an instance (the icon inside a
Close button, recoloured through an icon colour collection) wasn't an
override group. A full rebuild of the instance starts each layer over
from its main and carries only override groups, so the mode fell back
to the main's. Library import always rebuilds, as do main edits such as
a new auto layout direction, so a modal's recoloured close icon came
into other files in its default colour.
"modes" is now an override group: setting a mode inside an instance
records it, rebuilds carry it, rebasing a nested instance finds it, the
component panel lists it, and resetting it brings back the main's mode.
A top-level instance's own modes stay its own and record no override,
like its resizing.
An instance copied its main's variable modes when it was made and kept
the copy as modes of its own. Switching it to another variant kept the
old variant's modes, and a mode set on the main later never reached it.
Instances now take the modes their main sets through the link
(`Document::inherited_modes`), closer than any frame around them. Modes
set on the instance itself still win and stay through variant switches.
Bindings are re-applied for the instances of a main that chose another
mode and for an instance that switched mains. Detaching keeps the modes
the instance took from its main, and the Variable modes panel shows them
as the instance's Auto value.
Instances made before this change keep their copy as modes of their
own; setting one back to Auto lets it follow its main.
