feat(#22): Gate B BDFT identity and rounding (TV-3, TV-10)

Pure units module: bdft = sqft × thickness_in (no /12), half-up rounding for sqft/bdft/price, length to nearest 1/8". Property checks for monotonicity in thickness and sqft. TDD: red evidence in test-results/tv3-tv10-red.txt, then minimum impl. Results: TV-3 | pass | test-results/tv3-tv10-green.txt TV-10 | pass | test-results/tv3-tv10-green.txt
