让 webhook 渠道的入站 HTTP 回调真正进运行时（此前 handler 建了但未挂载，回调不达 runtime）。 - channelbridge：Bridge.WebhookHandlers() map[string]http.Handler——遍历适配器，对暴露 InboundHandler()/Config() 的（*webhook.Adapter）收集 endpointPath→handler。 - gateway/server.go：Deps 加 Webhooks map[string]http.Handler；Server 存 webhooks； Handler() 挂载到 mux（无网关鉴权，各 handler 自带 HMAC 签名校验）。 - gateway/static.go：spa 加 isWebhookRoute——已注册的 webhook 路径交给 API mux（否则被 SPA fallback 吞成 index.html，webhook 回调不达）。 - wire.go：gateway.Deps 传 Webhooks: a.channelBridge.WebhookHandlers()（wireChannels 在 wireFrontend 前执行，bridge 已建好）。 实机验证：POST /webhook 空体→bad_request(400,webhook 解码响应非 SPA)、带 JSON→accepted(200)、 GET /webhook 被 webhook 路由处理。go build/vet/test 全绿。
