test: 新增 benchmark 套件（test262 全量 + stress + 计时）

- build.sh：自动识别包管理器、装依赖、构建引擎与对照引擎
- run_benchmark.py：test262 全量 --no-skip、stress 基准、计时
- fetch_test262.sh：下载 test262 测试集
- README.md：用法说明

+脚本自动检测仓库内资源：
+- `../` — OxideJS Rust 源码
+- `../baseline-quickjs/` — QuickJS 源码（放这里自动编译）
+- `../tests/stress/` — JS 压测脚本
+- `../tests/test262/test/` — test262 套件（缺则运行 fetch_test262.sh）
+
+## 快速开始
+
+```bash
+# 1. 确保 QuickJS 源码在 baseline-quickjs/
+git submodule add https://github.com/bellard/quickjs.git baseline-quickjs
+# 或手动放入
+
+# 2. 确保 stress 测试在 tests/stress/
+# (仓库已自带)
+
+# 3. 构建
+bash benchmark/build.sh
+
+# 4. 下载 test262 (首次，约 500MB)
+bash benchmark/fetch_test262.sh
+
+# 5. 运行全量测试
+python3 benchmark/run_benchmark.py
