Add design spec for benchmark improvements: independent per-structure Gradle tasks via JavaExec, fast/precise mode split, JSON result storage, and regression comparison script. Update CLAUDE.md to require before/after benchmark comparison after every optimization change.
- Combine duplicate -jvmArgs into single string to prevent flag overwrite - Remove SimdEq from jmhSwissMap regex to eliminate overlap with jmhSimd - Unify SimdEqBenchmark to canonical @fork(2)/@Warmup/@measurement values - Set warmup time (-w 3s) and measurement time (-r 5s) in fast-mode tasks - Ignore docs/superpowers/ in .gitignore
