feat: add axe-core accessibility tests, performance benchmarks, update roadmap

- Add 9 axe-core accessibility tests for Shadcn primitives (Button, Card, Input, Label)
- Add performance benchmark suite (vitest bench) for core operations
- Update ROADMAP.md to reflect Q1 2026 completion (82% → 86% compliance)
- Install vitest-axe and axe-core as dev dependencies
