Rewrite Globe with pure refs, remove framer-motion dependency

- Remove useMotionValue/useSpring which caused effect re-runs
  and globe destroy/recreate cycles (source of glitches)
- All state tracked via refs (phi, drag offset, pointer position)
- Effect only re-runs on theme change, not on every spring tick
- Direct delta tracking for drag instead of spring physics
- Simpler, more stable WebGL lifecycle
