refactor(m109): rebase 到 5adac23 后按功能拆两条超 400 行的文件

rebase 到 M107/M108 之后的 main（5adac23），并集解冲突后 `app/state.rs`（401）与 `app/view.rs`（402）双双顶破 400 硬线。按功能拆，不压注释： - `app/state/boot_probe.rs`：启动期取证两件——`app_options`（启动参数 → 后端选项）与 `log_first_frame`（首帧耗时一行）+ 它们的两个全局量 `STARTED` / `FIRST_FRAME_LOGGED`； `state.rs` 用 `pub(crate) use` 再导出，`app/boot.rs`（`use super::state::STARTED`）与 `app/view.rs`（`log_first_frame`）的路径一字未变。state.rs 401 → 376。 - `app/view/tests.rs`：`view.rs` 的守门测试独立成文件（`#[path] mod tests;`）。**内容取自当前 main 的测试体**（M106 的 `Lang` 形参 / `at()` 入口都在），不是旧分支那一份；view.rs 402 → 255。 - `presenter/src/state/content.rs` 与 `presenter/src/state/content_tests.rs`：上一轮已拆，本轮不变。门禁（新 tip，`-j 2`，逐条前台跑并落盘退出码）：fmt 0 / clippy -D warnings 0 / `cargo test -p unlucky-app-iced --lib` 0（522 passed）/ `cargo test --workspace --exclude unlucky-app` 0。
