app_features

• Fix all static analysis lint issues: add missing return type annotations, use super.key parameters, and wrap angle brackets in doc comments with backticks.
• Remove unnecessary library directive.

• Add Feature Guards: per-feature redirect method that runs before route-level redirects.
• Add Async Initialization: Feature.init() hook + AppFeatures.configAsync() for async setup.
• Add Feature Middleware: onEnter/onLeave lifecycle hooks triggered automatically on navigation.
• Add Multi-Listener Events: Feature.on() now supports multiple callbacks per route name + off()/offAll().
• Add Global Event Bus: AppFeatures.on()/emit()/off() for cross-feature communication.
• Add Nested Features: Feature.subFeatures for automatic sub-feature registration.
• Rewrite example app to demonstrate all features: async init, feature guards, middleware, multi-listener events, global event bus, nested features, branch config, shell route config, dialog/bottom sheet routes, overlay utilities, scaffold messenger, and Material 3.

• BREAKING: upgrade go_router from ^16.0.0 to ^17.0.0.
• Bug Fix: fix routesWithRootKey losing onExit and caseSensitive properties when rebuilding routes.
• Bug Fix: fix refresh getter executing once at init instead of on each call.
• Bug Fix: fix typo in error message ("Future" to "Feature").

• Add all GoRouter constructor parameters to AppFeatures.config() (redirect, refreshListenable, onException, errorPageBuilder, errorBuilder, observers, debugLogDiagnostics, routerNeglect, overridePlatformDefaultLocation, initialExtra, redirectLimit, restorationScopeId, requestFocus, extraCodec).
• Add path-based navigation methods on Feature: pushPath, goPath, replacePath, pushReplacementPath.
• Add fragment parameter to Feature.go().
• Add static helpers on AppFeatures: namedLocation, go, push, state.
