## v0.5.1172 — feat(ui-windows-winui): render-backend dispatch seam + startup probe (#4680 step 3)

Builds on the Windows App SDK bootstrap probe. Adds `winui::backend` — the single
decision point the per-widget WinUI 3 mapping reads: `backend::active()` returns
`RenderBackend::Fluent` when the bootstrap probe is `Ready`, else `RenderBackend::Win32`.

A CRT static initializer (`.CRT$XCU`, anchored with `#[used]`) registered in the
crate runs the probe at process start for *any* binary that links this staticlib —
i.e. exactly the `--target windows-winui` builds, never the default `--target windows`
builds (which don't link the crate). So the first widget construction reads an
already-resolved backend rather than probing lazily. Setting `PERRY_WINUI_DIAG` prints
the chosen backend at launch (`[perry-winui] render backend: win32|fluent`) and, on
bootstrap failure, surfaces the raw HRESULT for diagnosis. The initializer never panics
(it runs before `main`).

Verified on a Windows host without the SDK: the initializer fires in a linked binary,
the `.CRT$XCU` section is present in the WHOLEARCHIVE'd `perry_ui_windows_winui.lib`, and
`active()` mirrors the bootstrap verdict and is stable across calls. Win32
(`--target windows`) remains the default and is unaffected.

## v0.5.1171 — fix(dayjs): `arguments` in sequence exprs + computed Date-method dispatch (#5133)

`compilePackages: dayjs` threw `ReferenceError: arguments is not defined`, and once that was resolved `.add()`/`.date(n)` silently no-op'd. Two distinct, general root causes:
