Windows startup crash is fixed, and packaging no longer drops modules
Windows crashed on startup in v0.29.34 through v0.29.36.
The 0.29.34 refactor moved wintray.py and tui.py to wintray/app.py and tui/app.py, but scripts/build_windows.ps1 still hidden-imported the old top-level module names. Because __init__.py in both packages is empty, PyInstaller only packaged empty shells and dropped the wintray dependency tree (panels.*, updates.*, and more). Every downloader hit ModuleNotFoundError: No module named 'wintray.app', and the TUI fallback failed because tui.app was also missing. macOS was unaffected because setup_app.py collects the whole package by name via py2app, which still matched after the rename.
