The real fix for "Citrine running but 0 connections": the app is served over
https in the WebView and Citrine listens on plaintext ws://127.0.0.1, which
modern Android WebViews block as mixed content BEFORE it reaches the network
layer — allowMixedContent + the loopback network-security-config don't fully
cover WebSocket mixed content.
MainActivity now sets the bridge WebView's mixed-content mode to
MIXED_CONTENT_ALWAYS_ALLOW after super.onCreate(), which lets the localhost
ws:// connection through for every user. All real traffic stays wss:///https://;
this only unblocks the loopback relay. The WebViewClient is left untouched
(overriding it previously caused a black screen). Wrapped in try/catch so it can
never crash the launcher.
Also removed the temporary on-screen probe debug readout (kept the diagnostic
fields in useCitrine, unused by UI, for future use).
