💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

🚀 Feature

Refactor subscriptions to stream-native APIs

Refactor subscription internals toward stream-native Dart APIs while keeping the existing DataPublisher and AbortSignal compatibility APIs available as deprecated APIs.

Added stream-native helpers for channel streams, demultiplexing, reactive stores, and data/error stream composition, and migrated internal subscription consumers to use Dart Stream/StreamSubscription flows where possible.
