feat(vim): conceal markup delimiters when conceallevel=2

Browse Source 
Set conceallevel=2 and concealcursor=nc on .wiki buffers and add
contained `conceal` matches for the bold/italic/code delimiters and
wikilink brackets/targets. The static-fallback rendering now mirrors
what the Neovim semantic-token path produced: *bold* shows as bold
without the asterisks, [[target|desc]] shows just "desc", etc.

The wikilink region uses an inline `contains=` (no line continuation)
because some Vim builds (notably Homebrew Vim 9.2) raise E10 on the
leading `\\ contains=...` form even though the surrounding region
parses fine.
