#!/usr/bin/env bash
# clean_outputs.sh — 清理编译输出与日志垃圾文件
#
# 用法:
#   clean_outputs.sh [选项]
#
# 选项:
#   --logs        清理 output/logs/ 下的运行日志（保留 last_run.txt / last_failed.txt）
#   --analyze     清理 output/analyze/ 下的单用例分析结果
#   --build       清理 build_lab*/ 构建目录
#   --test-result 清理 test/test_result/ 下的测试产物
#   --all         清理以上全部
#   --dry-run     只打印将要删除的内容，不实际删除
#   --yes         跳过确认提示，直接删除（配合 --logs / --all 等使用）
#
# 不带任何选项时交互式选择。
