passages: swept tube evaluates the exact route on in-bound cache misses (L100, v216)

L99 treated a missing exact-grid sweep sample as "no route here", so off-grid queries exposed the
FI/TN boundary band inside passage 1-2 (flat ceiling/floor). In-bound misses now evaluate the
exact route; a conservative route-feature bound still skips out-of-extent misses. Composition
order unchanged (graph -> bands -> passage -> stamps -> floor caps).
Comparison now counts added/removed crossings and triangles: 0/0 crossings on all four strates
(FI +56 triangles). 1-2 mid-tunnel: L98->L100 changes 32k px (L99 changed 1.14M).
Near-ready @W12 (L98/L99/L100): FI 2.62/1.78/2.05, TN 2.36/1.55/1.80, SW 1.17/0.95/1.04,
VS 1.16/1.03/1.08 s. All walk audits pass; 24/24 Clang/GCC W1/W8/W12 determinism; fast tier PASS.
