passages: two-pass swept-tube tunnels (owner design, L99, v215) - pending owner visual review

Route plan unchanged. Per tile, route segments whose bounded influence (tube + 4 m) touches the
tile write min-combined tube distance (base sweep); relief/floor/mouth shaping only in the shell
(detail sweep); 0.5 m edge blend into the strate field. Near-ready @W12: SW 1.01->0.80,
FI 2.23->1.43, TN 2.18->1.37, VS 1.09->0.98 s; whole view FI 3.38->2.37 s. All passage walk
audits pass (21,425/21,425 canonical, 3/3 interfaces); 24-run Clang/GCC W1/W8/W12 determinism;
0 sign flips. Change: mean 0.02 cm / 0.05 deg; max 25.9 cm (passage walls/roofs ~3.5 m from
route, LOD2) and 49.8 deg (rock walls 13-25 m from routes, LOD2). Captures with diffs in
Linux99/captures. Fast tier PASS (v215 pins).
