Move the crash-safe write-then-rename pattern into zesdex-utils::write_json_atomic and apply it across: - zesdex-cms: app_config_repo, conversation_repo, settings_repo - zesdex-iam: oauth_repo, session_repo - zesdex-entities: Conversation::save_conversation, Session::save Excluded (non-JSON format): - rewind_blob_repo (binary blob) - memory_repo (markdown + frontmatter, not JSON) - session_lock (PID string, not JSON) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
