apply_move no longer writes Facing (was the only movement-facing coupling,
player-only); the player's view changes solely via explicit SetFacing.
NPC path-follow now sets Facing to the step direction — a strict improvement
recorded as a D-252 correction: NPCs previously never received Facing from
movement, their cones sat at spawn direction while walking. Bump-to-turn
retired (blocked moves change nothing) with a regression test for each
semantic. Wire schema unchanged; player_facing docs now say view/aim.
Gauntlet fixtures regenerated (facing octants now reflect view-only
semantics); client replay + live-roundtrip suites green against the new
server.
