feat: Prometheus 监控集成 — /metrics 端点 + 14 指标 + 8 告警规则

- 新增 internal/metrics/metrics.go: 14 个 Prometheus 指标 - server.go: /metrics 替换为 promhttp, 15s 后台同步 - go.mod: 新增 client_golang v1.23.2 - deploy/prometheus.yml: 抓取配置 (zhiyid:7821) - deploy/prometheus-alerts.yml: 8 条告警规则 - deploy/prometheus.service: systemd unit

-### 7.4 vLLM BGE 本地部署
+### 7.4 BGE 嵌入部署

-Go 实施完成后，BGE 从模力方舟 API 迁移到本地 vLLM。详见 2.3 节部署步骤。
-
-```
-环境变量切换：BGE_ENDPOINT → http://localhost:8000/v1
-API 格式完全兼容，Go 代码无需改动
-```
+当前方案：Python ONNX Runtime（`bge-embed.service`），监听 `localhost:8000`，兼容 OpenAI `/v1/embeddings` 格式。后续可选迁移到 Rust `ort` crate（当前 `embed.rs` 占位）。
