feat(govai): 0617 优化首批 — 安全/私有化/深度研究/服务层/可观测性

借鉴 odysseus 的能力设计，全程净室实现、零 AGPL 代码、不引入 AGPL 依赖。 T1 提示注入防护: pkg/promptguard 包裹外部/知识库内容为不可信数据，buildMessages 移出 system 指令区。 T2 安全 CI: .github/workflows(ci+security: govulncheck/gitleaks/actionlint/hadolint/trivy)+dependabot+.hadolint.yaml；go.mod 加 toolchain go1.25.11 修复 20 个 stdlib CVE。 T3 管理员 2FA: 迁移 000016 + RFC6238 TOTP/备份码(pkg/auth, 零依赖) + 登录流程集成(后端)。 T4 本地模型: LLM/embedding 支持本地 vLLM/Ollama(OpenAI 兼容, 鉴权头条件发送, NoAuth) + docs/local-deploy.md。 T6 深度研究: 迁移 000017 + Python research-worker(净室多步流水线, 检索避开 SearXNG) + Go research 服务/handler/路由。 T7 service 层: 新增 internal/service/{research,twofa}, 2FA 业务逻辑从胖 handler 下沉, 接口注入可单测。 T10 缓存/可观测性: internal/cache(Redis+内存, 优雅降级) 接入 store 热点列表; Prometheus 指标+/metrics; docs/openapi.yaml。验证: go build/vet/test ./... 全绿(8 包); research-worker 12 单测过; 真实 PG 应用迁移并烟测。
