test: add benchmarks, Unicode edge cases, and stress tests
Performance benchmarks across all major APIs: - BenchmarkRender (depth 1/3/5/7 tree, full page) - BenchmarkImprint (small/large pipeline) - BenchmarkCompareVariants (2/3 variants) - BenchmarkLayout (C, HCF, HLCRF, nested, many children) - BenchmarkEach (10/100/1000 items) - BenchmarkResponsive, BenchmarkStripTags - Codegen: GenerateClass, TagToClassName, GenerateBundle, GenerateRegistration Edge case tests: - Unicode: emoji, RTL (Arabic/Hebrew), zero-width chars, mixed scripts - Deep nesting: 10/20 levels, mixed slot types - Large Each iterations: 1000/5000 items, nested Each - Layout variant validation: invalid chars, lowercase, duplicates, empty - Nil context handling for Render, Imprint, CompareVariants - Switch no-match, Entitled nil context, empty tag El Co-Authored-By: Virgil <virgil@lethean.io>
