Skyfuller1303 d331db00aa M1: keep explicit instance identity and cached library components in .fig import
A .fig import now links the layers of an instance to the layers of the
component they came from by the ids the file stores, instead of leaving it to
the engine to guess from names and places. Renamed slots and layers, siblings
that share a name and swapped mains keep their source link and the override
they carry.

Components that live only on the file's hidden internal pages (cached copies of
library components) are kept in the hidden library store when a visible layer
uses them, so their instances stay instances. The read-only guard for library
copies now compares the copies themselves rather than the dirty set, which an
import leaves full until the first edit.

Rebasing an instance (after detaching an outer instance or restoring a main)
follows the source chain inside the right enclosing instance, so contextual
links survive it. The last change of a GUID wins and a removed change deletes
it. Ordinary file JSON never reads the private provenance.

Importing such a file into an open document, or pasting its layers into another one, copies the cached components along (import) or leaves them behind as a missing main (paste), so no link points at a layer of the target.
