Research direction
Start by reading the existing SpillStore and the scalar btree/bitmap build paths, then review issues #7300 and #7302 for context. Trace how intermediate pages are represented and identify the btree page codec boundary. Done means scalar btree and bitmap builds spill intermediate pages through SpillStore under memory pressure.
