Windows builds failed on drive-letter paths, backslashes, POSIX-only process launching, Python scripts inside app.asar, and Chinese Python output. Narrow windows also allowed analysis controls to overlap the teacher pane.

This change fixes those paths/processes, extracts review scripts before Python execution, forces UTF-8 for offline speech, makes the board header responsive, and accepts the system OpenCL driver dependency. It prepares v0.4.22 and gates publication on tests, typechecks, teaching quality, release policy/version checks, and real NSIS installation/file-integrity/uninstallation checks for both Windows editions.

Validated on Windows 11 with RTX 5090 and AMD Radeon:

• Full suite: 327 passed, 4 platform skips, 0 failures; typechecking, production build and teaching-quality gates passed.
• Real OpenCL on NVIDIA and AMD, and CUDA on RTX 5090: 9/13/19 boards passed; clean NVRTC dependency/startup regression passed.
• Final standard and NVIDIA packaged E2E: 11/11 each, including responsive layouts, streaming, quick game analysis, trial variations, active cancellation/recovery, Chinese/space profiles and restart persistence. Both installed applications also passed the 11-step E2E.
• Packaged and installed offline speech/Python review: 4/4 per edition; real noncached Chinese WAV generation and app.asar script extraction/execution passed.
• Real NSIS installation in isolated temporary Chinese/space directories: 284/284 standard files and 305/305 NVIDIA files matched SHA-256; both uninstalled successfully. All four Windows distribution archives also passed clean native-runtime checks.
• Teacher tool-chain smoke with a local mock provider passed. Paid LLM/ChatGPT login, Fox synchronization and cloud services were not exercised.

The local workspace installation initially omitted DLLs; the identical artifacts installed completely in system temporary directories. Compression changes did not fix that workspace-only behavior and were not retained. The new installer gate checks every installed file instead of relying only on an exit code or app startup.
