feat(loader): real Natural Earth globe via d3-geo + topojson + world-atlas

Per user — GlobeLoader должен показывать реальные континенты (Asia/Africa/
Australia outline) с rotating orthographic projection, как в прототипе
Downloads/Globe loader/Globe Loader.html. Прошлая версия использовала
faked ellipses graticule — выглядело как абстрактные кольца, не как глобус.

Implementation:
- d3-geo.geoOrthographic + d3.geoPath для projection math
- topojson-client.feature для распаковки world-atlas land-110m
- dynamic import обоих deps + JSON — не блокирует main bundle, lazy chunk
- requestAnimationFrame loop пересчитывает d-attr на каждом кадре
  (8s per revolution per прототип, tilt -15° lean)
- LAND_CACHE module-level — повторные mount'ы не re-fetch
- CSS .globe-sphere rotation удалена — d3 projection делает работу,
  CSS transform distort'ила бы land mass (нет projection math)

Bundle hit: ~55kb (land-110m.json) + ~15kb gzipped (d3-geo + topojson) —
lazy chunk, fetched один раз и cached.
