AppMic v0.2 — UI and Productization Development Build

First major UI/product pass built around the Hotfix-F audio work.

• Windows-style light/dark interface work.
• App/Mic/Output meters and diagnostics.
• Per-app volume memory.
• Limiter / clip diagnostics.
• Reconnect/watchdog work.
• Smoother UI behavior and DPI-aware presentation.

Historical development build; later versions refined stability and state handling.
