Focus Flow 0.2.1

What's fixed

• The Windows installer now always creates a stable desktop shortcut and Start Menu shortcut.
• Release builds now generate the portable ZIP automatically instead of requiring a manual archive step.
• Repeated desktop clicks now reuse the existing app instance instead of starting duplicate Electron processes.
• Version bumped to 0.2.1 so installer, source tag, and release assets match.

Verification

• npm run dist
• 20/20 tests passed
• Local installed desktop shortcut now points to %LOCALAPPDATA%\Programs\focus-flow\Focus Flow.exe
• Repeated shortcut launch keeps the same Electron process group instead of spawning another copy
