LinkFlow v0.2.1

Highlights

• Added persistent pairing tokens, same-origin enforcement, authenticated LAN API/WebSocket/file access, and host-only sensitive operations.
• Added a Windows named mutex and runtime metadata for reliable single-instance behavior on the actual active port.
• Replaced port-based termination with a LinkFlow-only graceful shutdown endpoint.
• Added rotating persistent logs and a tray action to open the log.
• Enforced a 256 MB upload limit and made history clearing remove transferred files safely.
• Redesigned the LinkFlow logo as opposing half-arrows and synchronized tray, desktop shortcut, browser, PWA, and in-app icons.
• Added and expanded lifecycle, security, cleanup, and browser-activation regression tests.
