flutter_stasis_core 0.3.1

Pure Dart core of the Stasis ecosystem. StateObject, ViewModelState, Command, CommandPolicy and CommandResult — no Flutter, no third-party dependencies.

• Added debug assertions requiring policyKey for droppable, sequential, and restartable.
• Added fail-fast CommandContractViolationError when Command.call() throws instead of returning CommandResult.
• Expanded command policy docs with explicit restartable and droppable semantics.

0.3.0

• Pre-1.0 release line.
