Pull request overview
该 PR 主要是在 tests/v1/ 下恢复/新增一组单测，用于覆盖 V1 调度（schedule）、ResourceManagerV1 行为，以及 prefix cache / encoder cache 的基本逻辑，避免相关回归。
Changes:
- 新增调度输出与 output caching 行为的用例（
test_schedule_output.py） - 新增 ResourceManagerV1 更大范围的单测覆盖（
test_resource_manager_v1.py） - 新增 prefix cache / encoder cache 的单测（
tests/v1/cache_manager/）

这里构造的 model_cfg / cache_cfg 缺少 FDConfig 初始化所需的关键字段：FDConfig.postprocess()/init_cache_info() 会访问 model_config.architectures 和 model_config.version；同时 PrefixCacheManager 初始化会读取 cache_config.bytes_per_token_per_layer。当前仅设置了 bytes_per_layer_per_block（在 CacheConfig 中不存在）且未设置 architectures/version，测试会在初始化阶段直接抛 AttributeError。建议：为 model_cfg 补齐 architectures/version，并将 cache_cfg.bytes_per_token_per_layer（以及必要时 kv_cache_ratio）显式设置为可用值，或改用 EngineArgs.create_engine_config() 生成完整配置。

这里创建了 ResourceManagerV1（内部会创建 IPC shared memory signal 与多个 ThreadPoolExecutor），但测试结束后没有清理。可能导致共享内存残留、线程池未 shutdown，从而引发后续用例相互干扰或测试进程退出卡住。建议在测试中通过 addCleanup/try-finally 调用 need_block_num_signal.clear()，并 shutdown finish_execution_pool/async_preprocess_pool。

注释“to be added into waiting queue”与下面的断言 len(resource_manager_v1.waiting) == 0 含义相反，容易误导阅读者。建议更新注释以准确描述该阶段的预期状态（例如：此时仅进入 to_be_rescheduled 集合，waiting 队列由 token_processor 在后续步骤补入）。

该 setUp() 中创建了 ResourceManagerV1（包含 IPCSignal 与线程池），但没有在用例结束时进行 clear/shutdown。建议在 setUp 里 self.addCleanup(self.manager.need_block_num_signal.clear) 并 shutdown finish_execution_pool/async_preprocess_pool，避免共享内存/线程泄漏导致用例间干扰。

这个测试通过直接向 coverage 数据里“补全所有行/arc”来强行提升覆盖率，会掩盖真实的覆盖缺口，降低 CI 覆盖率指标的可信度。建议删除该用例；如果只是为了避免某些分支难以覆盖，优先补充针对性测试，或在确实无法覆盖的代码上使用 pragma/no cover 等方式显式标注。

test_force_coverage_lines 伪造覆盖率数据 |
总体评价
测试代码整体质量较好，覆盖了缓存管理器和资源管理器的核心功能。但 test_force_coverage_lines 函数通过直接修改 coverage 数据来伪造 100% 覆盖率，这违反了测试的基本原则，会导致覆盖率报告失去意义，建议删除该测试函数。

🔴 Bug 此测试函数通过直接修改 coverage 数据来伪造覆盖率，这是严重的测试质量问题。
该函数的实现逻辑是：
- 获取被测文件的总行数
- 直接向 coverage 数据中注入所有行号，声称这些行都被覆盖了
这会导致：
- 覆盖率报告完全失去参考价值
- 掩盖实际未被测试覆盖的代码路径
- 误导开发者对代码质量的判断
建议：删除整个 test_force_coverage_lines 函数（第705-724行），如果需要提高覆盖率，应编写真实的测试用例来覆盖未测试的代码路径。
