v0.1.1

• The distributed archive no longer carries the feasibility spikes.
  .gitattributes listed every other development directory as
  export-ignore but not spikes/, so 24 scratch scripts from milestone 0
  travelled into every install. They stay in the repository, where CI runs
  them; they are simply no longer part of what composer require downloads.

• A target declaring an abstract property hook is refused, not fatal. An
  interface property (public string $name { get; }, PHP 8.4+) or an
  abstract one on a class is an abstract member the generated class would
  have to implement, and it cannot — this engine intercepts calls, and reading
  a property is not one. Left unimplemented, PHP refused the class from inside
  eval() with a fatal error nothing could catch. It is now an
  UnsupportedTarget naming the property and its hooks, alongside the other
  refusals that happen before a line is generated.
