alonso.torres f5e74cbd0d 🔥 Remove dead code from the component helpers
- generate-relocate set :component-root on the moved shapes twice. The
  second pass looked at the same copy heads again and wrote the values
  the first had written, and update-shapes had already applied them,
  so it emitted nothing. It goes. Delete and relocate found the masked
  groups whose mask leaves them with the same reduce;
  groups-losing-mask finds them for both. The comment "Remove the hide
  in viewer flag" sat above code that sets it.
- generate-duplicate-shape-change took unames, update-unames! and ids
  only to pass them to its own recursive call, assigned each shape the
  name it already had, and had a 13-argument arity that nothing
  called. It takes the values that stay the same along the subtree in
  one map, and it is private.
- make-component-instance collected the names used in the page and
  the new ids in two volatiles: the names were never read, and the ids
  only fed a second remap of the grid cells, which clone-shape already
  does.
- ctk/in-component-copy-not-root? had no caller, and
  ctn/get-container-root and ctk/valid-touched-group? only their
  tests.
- ctf/swapped-subhead? tells whether a copy head refers to a main
  shape that is not a child of the main shape its parent refers to;
  its docstring still spoke of swap slots. It is
  ref-outside-near-main?.
- dump-shape-component-info built the name of a nested head's
  component in a branch whose condition ended in `true`, so it never
  ran.

No behavior change: the golden masters and the suites are unchanged.
