Pure, Three.js-free wall-local geometry that will power directly-visible
proximity guides for doors and windows (rendered in the follow-up phases):
- sill / head height (floor → bottom edge, top edge → wall top)
- edge-to-edge proximity clearance to the nearest neighbour on each side
(or the wall end), with overlap suppression
- along-wall alignment (edge/centre coincidence with a neighbour)
- vertical alignment (shared sill / centre / top — "same sill height")
- Figma-style equal-spacing run detection across a series of 3+ openings
Single `computeOpeningGuides` entry plus exported detectors; 23 unit tests.
Codex-reviewed — equal-spacing uses a longest-equal-window scan (a greedy
first-gap anchor dropped valid runs), edge gaps suppress straddling overlaps,
and the alignment detectors guard against the moving opening appearing in its
own sibling list.
