Add Windows support notice modal for Windows users on startup

Shows a modal on first launch for Windows users explaining that Windows
support is actively being improved. Features:
- Inline toggle to enable beta updates for latest bug fixes
- Link to report issues on GitHub (with note that vetted PRs welcome)
- Link to join Discord Windows-specific channel for community support
- Create Debug Package button for easy bug reporting
- Checkbox to suppress the modal for future sessions
- Console debug function: window.__showWindowsWarningModal()
