v1.4.90 P1-B: 注册一个 Prometheus extension renderer —— 见 [ExtraRenderer] 文档.

调用方：futu-server / futu-gateway 启动时调一次, 把自己持有的 GatewayMetrics (per-cmd push counter / 24-hour breakdown / push_health circuit breaker 等) 渲染成 Prometheus text 追加到 /metrics.

多次注册会保留所有 renderer; 顺序与注册顺序一致.

pub fn render_prometheus(&self) -> String

Prometheus text exposition 格式输出.

v1.4.106 codex 0542 F1 [P2 SECURITY]: key_id label 默认 redact 为 kh_<8hex> (短 SHA256). 设 FUTU_METRICS_PUBLIC=1 env 回退明文. 见 redact_key_id / Scope::MetricsRead.
