caffeine 2.0.0

A reactive microstore for Dart. Event-driven stateful stores, lazy derived state with automatic dependency tracking, glitch-free reactivity, and hierarchical scope-based lifecycle management.

2.0.0

• Event binding: passing an Event<T> in scope overrides binds it to that scope; fire() from the owning scope or any descendant broadcasts through the entire subtree, enabling global and semi-global event routing
• Unbound events default to root: unbound events broadcast from the root scope, consistent with how unbound stores are globally accessible; bind an event to an intermediate scope to restrict its broadcast to that subtree
• Automatic scope promotion: derived stores are now placed in the deepest scope that owns their dependencies rather than the requesting scope, so all reads within a subtree share one instance
• Constant derived stores live on root: derived stores with no dependencies are promoted to the root scope, consistent with unbound accum stores
• Event<T> now implements StoreOverride (extracted to override.dart to avoid circular imports)

1.0.0

Initial release.

• Store<S, E> — reactive state machine with pure update function and explicit effect streams
• Stateful<S> — lazy derived reactive value with automatic dependency tracking via Snapshot
• Scope — runtime that manages the reactive graph, dispatches events, executes effects, and controls store lifecycles
• StoreOverride — transparent store replacement for dependency injection and testing
• Scope forking for hierarchical store lifetime management
• External stream subscriptions via Store's subscribe parameter
• Glitch-free update compression: every Stateful node recomputes at most once per event cycle regardless of how many upstream dependencies changed
