feat(geom9 phase6): skeleton + миграция учебника Геометрия 9
Phase 6 — архитектурный skeleton нового интерактивного учебника 'Геометрия — 9 класс' (Казаков В.В., 2019). 16 параграфов, 4 главы. - Миграция 021_geometry_9_hub.sql: hub + 4 главы. Hub: rose-палитра, sort_order 8. ch1 amber (§1–§6), ch2 emerald (§7–§9), ch3 violet (§10–§12), ch4 cyan (§13–§16). - geometry_9_hub.html: rose/pink-палитра, 4 карточки глав, свернутый финал курса с placeholder для Phase 11. - geometry_9_ch1..ch4.html: полный skeleton по образцу algebra_9_ch4 — sidebars, search modal, achievement popup, XP/progress sync. Builder'ы — stub'ы 'В разработке (Phase 7)'. - backend/scripts/gen_geom9.js: вспомогательный генератор ch2–ch4 для воспроизводимости (одноразовый). Sample dark-theme palettes на каждую главу + SIDEBARS/TIPS с реальными краткими сводками формул учебника. Наполнение параграфов — следующими сессиями (Phase 7+).
