Adds OperatorCommandEvent + a closed command vocabulary (flatten_all,
flatten_symbol, pause_entries, resume_entries). POST /api/command emits it
(token-required: 503 when DASHBOARD_TOKEN unset — commands never run
unauthenticated); the live loop's new 5s "command" step consumes them via
OperatorCommandConsumer with three replay-safety layers (in-session nonce set,
persisted operator_command_done reload, 10-min staleness window).
flatten_all routes through close_session DIRECTLY (never step_eod_flatten) so it
cannot trip plan 003's daily-restart exit. Pause is checked at the top of BOTH
request_approvals_for_ready_signals AND submit_breakout_now (missing either
leaks pause on that path). qabot gains an authorized-chat-only /flatten slash
command (prose "flatten" still refuses via _ACTION_WORDS). Snapshot exposes
broker truth + command_bus + a defensive experiment ledger.
