Gravel

PebbleOS updates for Core watches now follow Core's public changelog, and Settings > About > Choose a PebbleOS build lists newer builds. Watchfaces and apps with internet access off run their code inside Gravel again where Gravel can block UDP. Where it cannot, such as on LineageOS, CalyxOS and Android 9 and older, a switch in Settings > Apps > Watch App Permissions, on by default, lets that code run with Android System WebView 152 or newer.

Fixes Gravel closing right after opening on LineageOS-based phones. For now, a watchface or watchapp with internet access off does not run its code inside Gravel; an update that brings this back is in progress.
