• Add [PruneCruft] to dist.ini so build artifacts (blib/,
  pm_to_blib, MYMETA.*) no longer leak into release tarballs.
  
• Add '@Class::Name' parent prefix to import (shortcut for use parent)
  
• Add '&Role::Name' role prefix to import (compose Role::Tiny role)
  
• Skip new injection when Object::HashBase is imported into a Role::Tiny role
  
• Role::Tiny is a soft requirement, loaded only when '&' prefix used
  
• '&' prefix requires Perl 5.10+
