Fix raw hooks: plugin-side hookRawMethod with Advice instrumentation

Remove the planted isContactsTabVisible() hook target and app-side visibility
conditionals (that was cheating). Plugins now declare raw JVM targets directly
via hookRawMethod on existing methods like MainScreenKt.selectMainPage,
ContactsTabKt.ContactsTab, NavigationBarKt.NavigationBarItem, and Logger.d.

Replace ByteBuddy MethodDelegation (schema-changing) with Advice-based
ClassReloadingStrategy so hooks actually install at runtime. Fix Logger hook
signature for Kotlin object instance methods. Add chat banner z-index fix and
PluginEngine.hostRevision to recompose MainScreen after plugin load.
