The plain-Vim client only defined VimwikiFollowLink; the split/vsplit/
tabnew/tabdrop/back command surface existed only in the Neovim branch.
Add :Vimwiki{Split,VSplit,Tabnew,TabDrop,GoBack}Link (+ :Nuwiki* aliases)
to the Vim branch, backed by a new nuwiki#commands#follow_link_drop()
helper that runs `:tab drop` to reuse an already-open tab.
Both clients now implement real tab-drop: open_uri gains a 'tabdrop'
case and M.follow_link_drop(); the Neovim TabDropLink commands and the
<C-S-CR> mappings (Vim + Lua) are repointed off the old tabnew cheat.
