test(hooks): finalize mutation test improvements and release acceptance
- Raise use-swipe-gesture mutation score to 66.13% (target 65%+) - Maintain use-reduced-motion mutation score at 76.32% (target 50%+) - Fix use-reduced-motion.ts ESLint set-state-in-effect warning - Add UJ-10 deep searcher journey (category browse → article read → content discovery) - Add 40 new test files (analytics, detail, sections, ui, lib components) - Update test-strategy-plan.md to v2.0 (sync test count to 1591) - Sync README.md with final release metrics Quality gates: TS 0 errors, ESLint 0 errors, 121 suites / 1591 tests passed
