  [BUG FIXES]

  - exceptions should not throw other exceptions; fixes cases where exceptions
    were reporting the wrong error (Upasana, RT#92818 and RT#94795)

  [OTHER]

  - prereqs needed strictly for building with Dist::Zilla have been moved from
    develop requires to develop recommends, to simplify automated testing on
    older perls that cannot install all Dist::Zilla components
  - removed instances of metaobjects in exception classes where they're not
    really required
