fix(mobile): keyboard lift via VisualViewport (measured gap, exact) not plugin height

Browse Source 
The Keyboard plugin's reported height overshot. With resize:none the WebView stays full-size, so
window.innerHeight - visualViewport.height is the EXACT keyboard overlap -> composer lands on the
keyboard. Web-only, works on the resize:none build already installed.
Build marker -> 2026-07-18-batch101.
