refactor(download): 纯搬移为 M289 腾出行数余量（config 单测 / engine 只读查询面）
两个文件都是 400 行零余量的硬线，本 mission 要加超时字段与失速诊断，先纯搬移： * `config.rs` 的 `#[cfg(test)] mod tests`（174 行）→ `config/tests.rs`， 原文件用 `#[cfg(test)] #[path = "config/tests.rs"] mod tests;` 声明； * `engine.rs` 的七个只读 getter（`config` / `concurrency_probe` / `client` / `region` / `mirrors` / `health` / `cache`，44 行）→ `engine/inspect.rs`。 逐字节未改：搬移块去缩进后与 HEAD 原文 `diff` 均为 exit 0。 行为零变化（同一批测试仍全绿）；新文件都在 `crates/core/src/download/**` 内， 外部路径（`download::config::EngineConfig` 等）不变。
