fix(render): near plane 1.0m -> 0.1m (retail Render::znear) - corner see-through-wall; file #107-#109

Browse source 
The collided camera eye sits 0.3m from walls (viewer_sphere radius); a 1.0m near plane clipped the wall face away, so pressing the camera into a corner showed the clear color through the wall (gate result: unchanged by the flood fix - it was never a flood bug). Retail sets Render::znear = 0.1 flat in SetFOVRad (decomp :342173, initializer :1101867). All four cameras aligned. Also files #107 (indoor spawn wedge, 3-for-3), #108 (cellar-up terrain sweep across door opening), #109 (exit-door texture/background oscillation) from the 2026-06-10 visual gate; gate confirms the dac8f6a flood fix: room-room + indoor-outdoor transitions clean.
