v0.4.0

• Added Gen::forParameters(\ReflectionFunctionAbstract $function, array $overrides = [], int $maxDepth = 3): generators for a function's parameters,
  by name in signature order — the forClass() resolution rules (override →
  @param psalm type → native type, same supported subset, refusals that name
  the function and the parameter) applied to any method or closure instead of a
  constructor. Overrides may be partial: the parameters they name are taken as
  given, the rest are derived from the signature. This is the engine half of
  the adapters' upcoming auto mode, where a fully-typed property needs no
  provider method at all.
