Replace CI benchmark with real-world AFFiNE dataset approach

- Updated .github/workflows/CI.yml to clone AFFiNE v0.23.2 directly in CI
- Install hyperfine for statistical benchmarking
- Collect JS/TS files from AFFiNE source as benchmark data
- Use new affine_bench binary instead of cargo bench
- Run both quick comparison and hyperfine statistical benchmarks
- Maintains aarch64 target optimization with native CPU flags
