- 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

feat(sdf): S11-B — SDF operations + domain deformations
CI / Build & Test (push) Failing after 38s
CI / Release Build (push) Failing after 31s
Add header-only SDF combinator operations and domain deformation
functions based on Inigo Quilez standard formulations:
Boolean operations:
- op_union (min), op_intersection (max), op_difference (max(-d1,d2))
- Smooth variants: op_smooth_union/intersection/difference with blend radius k
with graceful fallback to sharp when k <= 0
Shape modifiers:
- op_round (d - r), op_onion (abs(d) - t/2)
Domain deformations (coordinate remapping):
- op_repeat (infinite grid repetition)
- op_mirror_x/y/z (with optional offset)
- op_rotate (Y-axis), op_translate, op_scale
- op_twist (Y-axis), op_bend, op_cheap_bend
- op_elongate, op_displace
All functions are inline in include/vde/sdf/sdf_operations.h.
Comprehensive unit tests in tests/sdf/test_sdf_operations.cpp covering
sharp/smooth booleans, modifiers, domain ops, and composition tests.
