The three ways the height report flagged as guessed-height buildings are not
buildings: two are building=roof at layer=1 (elevated canopies) and one is an
amenity=shelter (public_transport). The report's '2 levels x 3.2 m' default
invented the 6.4 m figure. block_height_report.py now classifies them explicitly;
the block now reports 0 guessed heights, all 15 volumes having a real height tag,
a levels derivation, or a non-building classification.
Also records the measured hero proportions (colonnade 6.90 m = 47.6% of the
14.50 m envelope) for the open proportion task, which needs photo review.
