The nest assign_object API now removes existing spatial containment and
aggregate relationships before creating the nest, matching the behavior
documented in its docstring and consistent with aggregate.assign_object.

Walk up the full hierarchy via get_parent() in can_nest() and
can_aggregate() to reject assignments that would create a cycle.
Also reject self-assignment.

After assigning an IFC class and undoing, msgbus subscriptions registered
with the old Python object wrapper survived (PERSISTENT flag) but could
not be cleared because: (1) rollback_link_element looked up objects by
their post-link name which no longer exists after undo, and (2) the
per-object clear_by_owner calls in rebuild_element_maps used new Python
wrappers that didn't match the old subscription owners.
Fix by using a dedicated stable object (object_subscription_owner) as
the msgbus owner for all per-object subscriptions, allowing
rebuild_element_maps to clear all stale subscriptions in one call
regardless of Python wrapper identity changes during undo/redo.

The `is not ...` was being captured by the walrus assignment due to
missing parentheses, causing the condition to always evaluate incorrectly.

remove_representation_item now returns early if removing the item would
leave Items empty. edit_text_literals returns early on empty attributes.

add_boolean was removing second operands from ALL IfcShapeRepresentations
that referenced them, which could corrupt unrelated shapes and leave
representations with empty Items (bug #7803).
The API no longer modifies Items — callers manage this explicitly.
validate_type and Bonsai's AddBoolean operator now handle their own
item removal scoped to the correct representation.

remove_deep is deprecated and can silently delete elements still in use.
remove_deep2 requires zero inverses before removal, making it safer.
Also fixes a double-removal bug in remove_grid_axis and prevents
removing the last prop template from a pset template.

Tests using custom first/last tread runs were not setting
custom_tread_lock=False, so the custom values were silently ignored
since 8f7cf76d9 introduced the lock gate in the calculation.

SyntaxWarning: invalid escape sequence '\/' at line 312.
`\/` in a plain string is treated as `/` by accident; replaced with raw string r"..." to be explicit.
