Visual verification showed the camera vibrating/bouncing when pressed against a
wall. Cause: the sweep wrote its clamped result back into _dampedEye, so the
next frame's damping lerped from the wall toward the target and the sweep
re-clamped it — a per-frame feedback loop. Retail keeps viewer_sought_position
(damped, uncollided) separate from viewer (the published collided eye). Fix:
collide into a separate publishedEye for Position/View/fade and leave _dampedEye
as the clean sought position. New regression test
Update_CollisionDoesNotCorruptDampedState (clamp-then-release → full recovery).
