• fix: restore-to-stock-parent crashes on spec switch (#11)
  The do-restore snippet was calling b:SetParent(p) where p was the
  ActionButton's original Blizzard bar (MultiBarBottomRight, etc.),
  captured via btn:GetParent() at file-load time. In WoW 12.0's
  restricted execution environment these stock bar frames are protected
  but not "explicitly protected" for SetParent targeting, so the
  restricted env rejects the unwrapped handle and throws:
  RestrictedFrames.lua:622: Invalid frame handle for SetParent
  This fired on the first spec switch (RebuildDisplay -> TeardownDisplay
  -> DestroyActionColumn -> SetAttribute("do-restore", ...)).
  Cross-checked EllesmereUI: it never restores to stock bar parents and
  only SetParents to frames it owns (hiddenParent, UIParent). Strong
  evidence that "restore to stock parent" is not a viable pattern in
  12.0's restricted env.
  Fix: change do-restore to just Hide() the buttons. They remain parented
  to UIParent (where do-setup put them) in a neutral hidden state. The
  next spec's do-setup repositions and Shows whichever buttons the new
  spec needs. Drops the origParents cache and orig-N frame refs entirely
  since they served no other purpose.
  Trade-off: on addon disable without /reload, buttons used by the active
  spec stay hidden on the bar until reload (they don't return to stock
  positions). Previously they also didn't return — the restore simply
  crashed. Spec switches (the common case) are fully fixed.
