Problem

mksession treats buftype='acwrite' buffers as blank windows when blank is excluded from sessionoptions, causing canola windows to be silently omitted from saved sessions.

Solution

Clear buftype on all canola buffers in VimLeavePre so the session writer sees them as regular file buffers and saves their canola:// URLs. On restore, BufReadCmd re-initializes them normally. Mid-session :mksession calls are not yet covered — blocked by neovim/neovim#22814.

Canola-branch counterpart of #195. Closes #149.
