Add a ListSyms type (vimwiki's g:vimwiki_listsyms) and thread it through the lexer so checkbox glyphs are recognized from the configured palette rather than the hardcoded ' .oOX'. Glyphs map to the existing five-bucket CheckboxState, so the HTML renderer and AST consumers are unchanged. VimwikiSyntax::parse_with_listsyms opts into a custom palette; the trait parse() keeps the default. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
