feat(client): cutaway modes — corridor / bottom-walls-low / both, C-key live toggle (T-1088)
Live-session two-minds resolution: the trippy sightline corridor stays as a mode (candidate signature look); mode 1 drops any wall with a KNOWN non-wall tile on its camera-far side to the stub (X2 bottom-walls read — the player sees the room without walking to it); mode 2 combines. Bottom-wall flag rides MultiMesh INSTANCE_CUSTOM.r, updated on paint and when newly-learned floors promote camera-ward walls; camera-far directions derived from the live WorldRoot basis, never hand-derived. Default stays corridor pending the feel verdict. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
