- diary.vim: correct calendar_action doc comment (dir is used for split
direction; only week is unused)
- calendar-vim-integration.md: use real nuwiki var names
(g:nuwiki_use_calendar / g:nuwiki_no_calendar / g:nuwiki_wikis), document
auto-detect wiring and calendar-window close behavior; drop the
non-existent refresh-on-close autocmd
- vimwiki-gap.md: remove stale 'no calendar.vim integration' entry now
that the integration is implemented
