style(website): cut the padding from the page copy

Remove three cross-page duplications: the "what --help cannot say" list
appeared on both home and docs, the config precedence rule twice on
install, and the soulfind link twice in adjacent community paragraphs.

Drop the em dashes, the adverbs, and the rhetorical triads while there.
