feat(v11): CI/CD + regression tests + fuzzing + benchmarks + code quality
v11.1 — Test Infrastructure (14 files): - .github/workflows/ci.yml: Ubuntu 22.04 + GCC 11, auto ctest on push - tests/regression/: degenerate geometry, extreme coords, thin wall, large models - tests/fuzz/: SDF random CSG, random booleans, format round-trip, continuous mode - tests/benchmark/: boolean perf, MC perf, IO perf benchmarks - docs/benchmark-report.md: benchmark template v11.2 — Code Quality + Docs: - .clang-tidy: 15 check categories, 22 exclusions - .github/workflows/static-analysis.yml: clang-tidy CI scan - CODEOWNERS, SECURITY.md - docs: API overview, testing guide, contributing guide - README: module capability overview table Pending: binary formats + curve projection (retrying)
