- src/index.ts: VisionConfig 新增 sessionId，createVisionModel 注入 x-langfuse-session-id / x-langfuse-tags headers
- src/product-detector.ts: createVisionModel 同步注入 session headers
- src/post-filter.ts: createModel 同步注入 session headers
- scripts/run.ts: 支持 --session-id CLI 参数，fallback 自动生成
- 删除 VISION_API_KEY / VISION_API_BASE / ONEBOUND_* 死代码（统一由 auth-rt client-config 下发）
