Assist: remap bead prefixes, add open/defer; orphan: skip user-claimed

Tasks window Put handler prefix changes:
  ~ → c  (claim)
  ^ → u  (unclaim)
  o      (open/promote deferred)
  d      (defer)
  x, f, -, + unchanged

Orphan check now skips beads claimed by "user" — human-held beads
are not orphans.
