feat(sdf): S11 — SDF 隐式建模完整模块
S11-A: SDF 图元库
- 14 种基础形状(inline header)
- sphere/box/round_box/torus/capsule/cylinder/cone/plane/ellipsoid
- triangular_prism/hex_prism/link/wedge
- 2D 挤出(extrusion/extrusion_bounded/revolution)

S11-B: SDF 操作 + 域变形
- 锐利布尔: union/intersection/difference
- 平滑布尔: smooth_union/smooth_intersection/smooth_difference
- 修饰器: round/onion
- 域变形: repeat/mirror/rotate/translate/scale/twist/bend/elongate/displace/cheap_bend
- 24 项测试

S11-C: CSG 表达式树 + 网格转换 + Python 绑定
- SdfNode 树结构 — 工厂构造函数,递归求值
- sdf_to_mesh — 基于 marching_cubes 的 SDF→网格
- bind_sdf — pybind11 Python 绑定
