Compose an ordered layer stack (weakest first, strongest last — the same
order composeIfcx resolves "later wins") and materialize the result as
a flat, tombstone-free IFCX document.
The output carries no ifclite::bookkeeping: deletion overlays are
resolved (deleted subtrees are gone) and derived-cache markers are
dropped, while persistent data carriers (classifications, materials,
geometry refs) survive. Inherits are resolved into plain attributes.
