potluck, diigo-cache: docs one line per paragraph; potluck deploy caveat

Obsidian and GitHub render each newline as a line break, so the
hard-wrapped READMEs and CONTRIBUTINGs rendered ragged. Whitespace
only, except a note in potluck's CONTRIBUTING that other workerd
hosts are untested: they'd have to supply the D1 and R2 bindings.
