diff() looked up common elements with self.old.by_id(global_id) /
self.new.by_id(global_id), passing a GlobalId string into a method
that expects a STEP integer id. On v0.8.0 file.by_id() was a Python
wrapper that transparently dispatched strings to by_guid(), so the
bug was silent. v0.9.0's file class binds by_id directly to the
C++ instance_by_id(int), so it now raises
TypeError: in method 'file_by_id', argument 2 of type 'int'.
DeepDiff's dictionary_item_added/set_item_added results are a
deepdiff.helper.SetOrdered instance, which subclasses orderly_set's
StableSetEq rather than the OrderedSet class json_dump_default checked
for, so the property relationship check always crashed export() with
"Object of type SetOrdered is not JSON serializable". Check against
StableSet, the common base class shared by every orderly_set set
flavour, instead.

IfcDiff defaulted to relationships=["geometry"], so a plain diff only ever
compared geometry. Attribute-only edits on an element that kept its GlobalId
(a modified or removed PredefinedType, a renamed element, etc.) were silently
missed. The CLI made this worse: --relationships did not list "attributes" or
"geometry" as valid values, so there was no documented way to enable it.
The default is now ["attributes", "geometry"], so a plain `ifcdiff old new`
reports attribute changes alongside geometry changes. The CLI help and the
IfcDiff docstring now document all valid relationship values.
Added a regression test covering a PredefinedType change detected with the
default configuration.
