feat(client): wire full Vimwiki command-parity surface

Register the named :Vimwiki*/:Nuwiki* entry points that previously
existed only as mappings or were missing entirely — including
RemoveSingleCB/RemoveCBInList, CatUrl, TabMakeDiaryNote,
NormalizeLink, Renumber{List,AllLists}, TableAlign, ChangeSymbol(InList),
ListToggle, Increment/DecrementListItem, and the DeleteLink/RenameLink/
GenerateTags compat aliases. Both the Vim (vim-lsp/coc) and Neovim
client functions are added to back them.
