feat(geom11 phase0): skeleton + миграция + мини-3D движок g3d.js

Browse Source 
- 026_geometry_11_hub.sql: hub geometry-11 (cyan, 11 параграфов) + 4 раздела
  (Призма и цилиндр, Пирамида и конус, Сфера и шар, Повторение).
- frontend/js/g3d.js: мини-3D движок для стереометрии.
  Векторная математика, матрицы 3x3, перспективная + изометрическая проекции,
  меши призмы/пирамиды/цилиндра/конуса, wireframe сферы, back-face culling
  через нормали, Z-sort, drag-to-rotate (mouse + touch), preset views.
- frontend/textbooks/geometry_11_hub.html: hub с палитрой cyan/sky,
  4 карточками разделов, аккордеон финала курса (placeholder Phase 5).
- frontend/textbooks/geometry_11_ch{1..4}.html: skeleton 4 разделов
  (через gen_geom11_chapters.js). Все включают: помощники KaTeX, SVG 2D
  (axes2D/plotFunc/pointWithDrop/asymptote/rightAngleMark/angleArcAuto/unitVec),
  ICONS, makeCard, setupSorter, gcd, wireReadBtn, secNav, search, sidebar,
  GEOM11 POLISH CSS + JS, подключение /js/g3d.js. STUB builder для всех 11
  параграфов + 4 финалов с demo-G3D viewer (призма/цилиндр/пирамида/конус/
  сфера-wireframe).
