Adds a dark expanding sphere around the repair model when the player enters the immersive repair phases (fragmented / scanning / repairing / reassembling). The bubble grows from 0 to 10m using GSAP expo.out over 2.5s and reverses on focus end, visually isolating the player from the surrounding map. - New useRepairFocusStore tracks active state + world center. - New RepairFocusBubble renders a BackSide sphere shell + a soft cocoon decor pass (grid floor + directional light + ambient) inside. - RepairGame drives setFocus from its lifecycle effect. - Mounted in both GameStageContent and TestMap so behaviour matches in the production scene and the physics test scene. Also drops the now-unused EBIKE_CONFIG_KEY constant in GameStageContent.tsx (leftover from a previous remount-key strategy).
