[CLAUDE] Docs: S56 closeout — pre-golive verify + golive-harden + doc-drift + gotcha #58

STATUS/HANDOFF S56 + session log: WF1 pre-golive-verify (7-stream → GO) + WF2 golive-harden (4 fix, code a20cde8 Run #379 PASS). Test 216→228. Code golive-ready; 2 ops VPS pending (IT user + tzutil); FE Phase 2 deferred.

§L closeout (H1/H2): database-agent executed-file→verified-runtime (agents/README:4, D1 closed); ef-core skill 47→48; sys.tables 92→93 reconciled (cicd ground-truth); root CLAUDE test 203→228 + 92→93 bảng; gotcha #58 NEW (EF read-modify-write lost-update→ExecuteUpdate atomic). agent-memory harvest: cicd Run#379 + Fidelity Serializable-correction (impl/test MEMORY, H2 GATE 4.5/5).
