fix(extract): Mindestbreite gegen papierdünne und wandartige Gebäudegrundrisse

727 von 2.286 rohen Grundrissen (31,8 %, aber nur 1,8 % der bebauten Fläche) sind
unter 4 m an der kurzen Seite ihres gedrehten Hüllrechtecks — extrudiert werden
daraus Wände, keine Häuser. Eine Mindestbreite allein reicht nicht: einzelne Formen
bleiben bei >= 4 m Breite trotzdem extrem lang und dünn (z.B. 4,27 m x 153 m,
Verhältnis 35,9). MAX_ASPECT_RATIO=12 ergänzt die Mindestbreite MIN_BUILDING_WIDTH=4,
an einer echten Lücke in den gemessenen Verhältnissen festgemacht (größte plausible
große Grundfläche: Verhältnis 10,8 bei 7.196 m²; nächste eindeutig wandartige Form:
Verhältnis 12,0 bei 60,5 m²). Zusammen fallen 766 Grundrisse (33,5 %, 36.986 m² =
3,3 % der Fläche) weg.

Bestehende Fixture in test_small_staircase_building_is_not_dropped vergrößert (4x4-
auf 6x6-Block): ihre kurze Seite lag zufällig bei ~3,7 m, unter der neuen Schwelle,
und hätte den Test sonst für den falschen Grund bestehen lassen (Ruling 74 statt
Ruling 28).

Pipeline neu durchgelaufen: eindeutige Gebäude 2.282 -> 1.520 (-33,4 %), Dreiecke
über alle 144 Chunks 327.181 -> 307.678 (-6,0 %, vollständig aus der Gebäude-Ebene),
public/data/vice-a 2,73 M -> 2,50 M.
