1.0.0

Added

• Core reactives: Reactive<T> mutable signal with custom equality, freeze, peek, update, snapshot, and read-only view.
• Computed values: Computed<T> with lazy evaluation, caching, automatic dependency tracking, circular dependency detection, and custom equality.
• Effects: Effect with auto-tracking, debounce, throttle, re-entrancy protection, and watch() convenience function.
• Batching: ReactiveBatch with nested batch support, deduplication, and error collection via BatchException.
• Dependency tracking: ReactiveContext stack-based tracker with nested frames and untracked() escape hatch.
• Subscriptions: ReactiveSubscription disposable listener and SubscriptionGroup for bulk management.
• Lifecycle: ReactiveLifecycle mixin with onDispose, onChange, and ReactiveLifecycleState (created → active → disposed).
• Error types: ReactiveException, DisposedAccessException, FrozenReactiveException, ReadOnlyReactiveException, CircularDependencyException.
• Async state: Sealed AsyncState<T> with AsyncLoading, AsyncData, AsyncError, pattern matching (when, maybeWhen), and map.
• AsyncReactive: Reactive async operation wrapper with race condition prevention, refresh, and optimistic state updates.
• Resource: Async data fetching with cache duration, stale-while-revalidate, invalidation, force fetch, and optimistic updates.
• Reactive collections: ReactiveList<E>, ReactiveMap<K, V>, ReactiveSet<E> implementing full Dart collection interfaces with batching, freezing, snapshot, and dependency tracking.
• DI integration: Extensions on ServiceCollection and ServiceProviderBase for registering and resolving reactive types with davianspace_dependencyinjection.
• Flutter widgets: ReactiveBuilder (auto-tracking), ReactiveSelector (optimized selective rebuild), ReactiveScope (auto-disposing scope) with ScopeOwner.
• DevTools: ReactiveDebugLogger with ring buffer and GraphInspector with leak detection, disposed-node detection, and performance reporting.
• Extensions: toReactiveList(), toReactiveMap(), toReactiveSet(), disposeAll(), active, toReactive(), toAsyncReactive(), asStream(), asBroadcastStream().
