English Verify whether the optional-dependency Arborist fixtures still need to be skipped. The current code already has optional-failure tolerance in registry resolution, non-registry resolution, package materialization, and lifecycle script execution. Some skip comments in the Arborist runner may now be outdated. Scope Check the fixtures currently listed under optional-transitive skip in e2e/pm-arborist.sh. If they pass, remove them from the skip list. Update e2e/pm/arborist/README.md so the TODO list matches current behavior. Add a lightweight regression note or test if needed. Acceptance Criteria Each optional fixture is either unskipped or has an updated, code-confirmed skip reason. The README no longer claims unsupported behavior that is already implemented. The Arborist runner remains green for the supported fixture set. 中文 验证 Arborist 中 optional dependency 相关 fixture 是否仍然需要 skip。 当前代码已经在 registry 解析、非 registry 解析、包物

English Add a lightweight package-lock validation step to the Arborist E2E runner. The current runner mostly checks whether install exits successfully and whether node_modules or package-lock.json exists. We should also verify that generated lockfiles are valid JSON. Scope Update e2e/pm-arborist.sh. After successful install, if package-lock.json exists, validate it with Node.js JSON parsing. Print the fixture name on failure. Keep validation lightweight. Acceptance Criteria Invalid package-lock.json fails the fixture. Valid lockfiles continue to pass. The runner output clearly identifies the failing fixture. 中文 为 Arborist E2E runner 增加轻量级 package-lock.json 校验。 当前 runner 主要检查 install 是否成功，以及 node_modules 或 package-lock.json 是否存在。可以进一步校验生成的 lockfile 是否是合法 JSON。 任务范围 修改 e2e/pm-arborist.sh。 成功安装后，如果存在 package-lock.json，用 Node.js 做 JSON 解析校验。 失

English Expand test coverage for cache-clean matching logic. utoo clean supports package/version patterns, including scoped packages. The matching behavior should be covered more thoroughly. Scope Add tests for regular packages. Add tests for scoped packages like @types/node. Add wildcard matching tests. Verify collected cache entries are sorted deterministically. Acceptance Criteria Scoped and unscoped cache entries are both covered. Wildcard behavior is tested. Sorting behavior is tested. Tests pass. 中文 补充 utoo clean 缓存匹配逻辑的测试覆盖。 utoo clean 支持包名和版本通配，也需要覆盖 scoped package 场景。 任务范围 补充普通包测试。 补充 @types/node 这类 scoped package 测试。 补充通配符匹配测试。 验证收集到的缓存条目排序稳定。 验收标准 普通包和 scoped package 都有测试覆盖。 通配符行为有测试覆盖。 排序行为有测试覆盖。 测试通过。

English Improve test coverage for shell completion generation and shell detection. detect_shell_from_env currently detects common shells from $SHELL. This is a small, well-scoped area for new contributors. Scope Refactor shell-name detection into a small testable helper if needed. Add tests for bash, zsh, and fish. Add tests for unsupported shells. Keep completion generation behavior unchanged. Acceptance Criteria Supported shells are detected correctly. Unsupported shells return None. Completion generation tests still pass. 中文 补强 shell completion 生成与 shell 检测的测试覆盖。 当前 detect_shell_from_env 会从 $SHELL 检测常见 shell。这块逻辑范围小，适合新贡献者上手。 任务范围 如有需要，将 shell 名称检测拆成更容易测试的小函数。 补充 bash、zsh、fish 的测试。 补充不支持 shell 的测试。 不改变 completion 生成行为。 验收标准 支持的 shell 能正确识别。 不支持的 shell 返回 Non

English Add npm-compatible aliases for the uninstall command. Currently utoo supports utoo uninstall and utoo un. Adding remove and rm makes the CLI easier for npm users to discover. Scope Add utoo remove <pkg> alias. Add utoo rm <pkg> alias. Keep existing utoo uninstall and utoo un behavior unchanged. Add CLI parsing tests. Acceptance Criteria utoo remove lodash parses as uninstall. utoo rm lodash parses as uninstall. Existing aliases still work. Tests pass. 中文 为卸载命令增加 npm 兼容别名。 目前 utoo 支持 utoo uninstall 和 utoo un。增加 remove / rm 后，npm 用户更容易上手。 任务范围 增加 utoo remove <pkg> 别名。 增加 utoo rm <pkg> 别名。 保持现有 utoo uninstall 和 utoo un 行为不变。 补充 CLI 解析测试。 验收标准 utoo remove lodash 能解析为卸载命令。 utoo rm lodash 能解析为卸载命令。 现有别名仍然可用。 测试通过。
