The Optimise recipe imported `toposort`, a third-party PyPI package that
is not bundled with Bonsai, so running the recipe there raised
`ModuleNotFoundError: No module named 'toposort'`.
Replace it with the standard library `graphlib.TopologicalSorter`
(available since Python 3.9), which provides the same dependencies-first
ordering guarantee the recipe relies on: forward-referenced instances are
mapped before the instances that reference them. The dependency-graph
dict format ({node: {predecessors}}) is identical between the two, so the
graph construction is unchanged. Drop `toposort` from ifcpatch's
dependencies since it is no longer used.
Verified with toposort NOT installed: the Optimise recipe now runs and
deduplicates correctly (IfcParseExamples_test.ifc 88 -> 63 instances, all
6 products preserved, output reopens cleanly).
