🚀 New Features

• Decoupled & Generalized SignalProvider: Decoupled SignalProvider from FlutterReadonlySignal (which implements Listenable) and generalized it to accept any standard core ReadonlySignal from signals_core.
• Automatic Listenable Adapter Conversion: Standard signals that do not implement Listenable are automatically wrapped in a lightweight, lifecycle-managed Listenable adapter internally under InheritedNotifier, maintaining maximum efficiency without manual boilerplate.

🐛 Bug Fixes

• Dependency Injection Guide: Fixed primitive type compile errors and generic alignment inside docs/content/guides/dependency-injection.md.

⚠️ BREAKING CHANGES

• SignalBuilder Constructor: Updated SignalBuilder to accept a required named parameter required Widget Function(BuildContext) builder instead of a positional function argument. This aligns it perfectly as a drop-in replacement for Flutter's native Builder widget.

🚀 New Features

• SignalProvider & MultiSignalProvider Stateful Lifecycle: Completely redesigned SignalProvider as a StatefulWidget to maintain the reactive signal instance across parent rebuild cycles. Adds automatic dispose() teardown of created signals when unmounted, custom dispose callback support, and SignalProvider.value constructor to expose managed signals without teardown. Also adds SignalProvider.multi / MultiSignalProvider to flatten deeply nested builder hierarchies into a convenient flat list.
• SignalWidget & SignalStatefulWidget: Added stateless and stateful base widgets that establish implicit reactive contexts directly at the element layer. Any signal value accessed synchronously via .value in their build() methods will automatically schedule surgical, frame-coalesced rebuilds.
• SignalAnimatedBuilder: Added a modern transition builder widget designed for subtree rendering optimization. Accepts an optional pre-built static child widget which is cached and never rebuilt when signal values mutate.
• SignalEffect / SignalListener: Added inline side-effects widgets that run reactive callbacks (e.g. snackbars, dialog triggers, routing) when tracked signals mutate. Handles setup, callback updates, and cleanup automatically on unmount.
• SignalCustomPaint & SignalPainterWidget: Added canvas drawing targets that bypass element rebuild cycles by listening directly to signals at the rendering layer to trigger markNeedsPaint() directly.
• Widget & Element Conversion Options: Added toSignalWidget() on StatelessWidget and toSignalStatefulWidget() on StatefulWidget to seamlessly upgrade standard widgets to reactive versions. Also added watchSignal extensions on StatelessElement and StatefulElement.

⚡ Deprecations & Optimizations

• Deprecated legacy Watch, WatchBuilder, SignalsMixin, and the .watch(context) context watch extensions.
• Modernized legacy Watch and WatchBuilder under the hood to act as lightweight, stateless adapters delegating directly to SignalBuilder and SignalAnimatedBuilder to achieve zero-allocation state overhead.
• Optimized .watch(context) extension with a memory-safe Expando/WeakReference/Finalizer engine preventing lapsed-listener memory leaks and object identity hash collisions.
