Build: require 64-bit Windows — PlatformTarget x64 in app + tests (bundled ffmpeg is win64, ONNX Runtime has no win-x86, 32-bit address space can't hold 1080p buffers) (Unit: 64-bit requirement)

 - `onnxruntime.dll` is ~17 MB; an RID-less build copies every RID's native folder — TASK 48's MSIX
  publish must pin win-x64.
- `THIRD-PARTY-NOTICES.txt` header still says "paid, closed-source product" (pre free-forever) — noted,

+  release) — the creator is choosing the license; rewrite those with it.
 - Carried: "Use default background" toggle still not working (from 2026-10-07).
