docs(keycloak-session-store): take the sentences out of the diagram canvases

The skill says drawings carry names and sentences go in <desc> and the
paragraph beside the figure. I put sentences in node details and edge labels
instead, and 27 of the 28 diagrams shipped with prose inside the canvas —
"예측 다섯 개가 틀렸다", "아홉 번 조용히 실패했다", "막혀서 닿지 않는다".

Only label and details render on the canvas; description does not. So every
sentence moved to a noun phrase and the meaning stays in description, which
was already carrying it.

  막혀서 닿지 않는다              -> 차단
  아홉 번 조용히 실패했다         -> 조용한 실패 9건
  예측 다섯 개가 틀렸다           -> 틀린 예측 5건
  로그아웃이 정리하지 않는다      -> 로그아웃 미정리
  볼륨이 없으면 여기까지다        -> 볼륨 없음

Three node labels were sentences too and became names: 세션 스냅샷, 예측
선기록, 대조군 확보.

What stays is what the rules protect — identifiers, commands and measured
values: PRIMARY KEY (client_registration_id, principal_name),
ValidationFailedException: 1 changesets check sum, nginx -t && nginx -s
reload, SET LOCAL synchronous_commit TO OFF. Those are names of things, not
prose about them.

294 canvas strings across 28 diagrams, none matching a sentence ending,
average 11 characters. All 28 still lint clean and re-rendered.
