docs: close nine gaps found by re-reading every open question in full

Cross-checked each question's 남은 미지수, 다음 검증 and 제약 against the plan item by item. Adds B-0 (autoconfiguration actually chosen), B-6 (encryption key rotation) and B-7 (oauth2-proxy cookie secret rotation) as new experiments, plus lock-holder death, rotation-disabled comparison, partial-logout recovery, store latency and the Q4 design checklist. Restores the Redis persistence comparison and records the correct index URL.
