passages: exact density-aware outer bound skips passage work beyond its reach (L81, v214)

The carve is max(source, -roughSDF/Q), so its reach grows with -source; the outer test uses
-d*Q + 0.24 m (wall relief 0.21 + margin) beyond the route radius, disabled in mouth-support
and column-overlap tiles. Skips 16% of passage iterations on the highest-activity tiles and
all of them on ordinary tiles. 84 candidate/full pairs identical in every hash; 0 changed samples.
Evaluator 214 for cache invalidation only. Cold LOD0-2 (L80 protocol): SW 1.30->1.25,
FI 3.59->2.93, TN 3.18->3.51 (noise?), VS 1.33->1.22 s. Fast tier PASS.

Note: the export's legacy 26-point root route owner_world.passages[0] fails a full-view
pre-audit (65 solid samples, unchanged since L70); the canonical 211-point route used by the
plan passes. Stale data to clean up.
