The drop-in baseline preserves framework backward-compatibility contracts by recording expected defaults and states.
Explicit value comparisons are enforced and omitted snapshot entries are reported to detect unintended default modifications.
* DropInSnapshot:
* Record booleans, numbers and strings by value.
* Serialize plain objects with sorted keys, and record functions
and circular references without raising an exception.
* Extract DropInViewState, and isolate each getter so that an
exception leaves the remaining state intact.
* Add throwIfError, so that a generator does not save an exception
as expected state.
* Add a skipped list that names each class or window style left out
of a snapshot.
* Add DropInCibTree, with view, menu and object descriptions and a
cib owner, to describe the objects a cib produces.
* DropInBaselineGenerator: Pass throwIfError and print each skipped
entry.
* DropInBaseline: Regenerate with recorded values and sorted keys.
