Fixes the 'genuine' bucket from #4040's triage: whitelist/allowlist
(6 hits across 5 files, including a heading rename in turn-loop/mcp.md
-- checked no anchor links reference it first) and the
simply/obvious/easy condescending-word cluster (10 of 13 hits, real
sentence-level rewrites rather than mechanical deletion so nothing
reads awkwardly).
Left 3 alex.Condescending hits untouched on purpose:
integrations/matrix.md:271 and process/conventions.md:442 both say
"non-obvious", swarm/ca.md:162 says "not obvious" -- alex matched
the substring "obvious" inside a negated phrase, the literal opposite
of condescending. Flagging these on the issue rather than silently
leaving them out.
