Inline comments:
Review comments at @server/src/routes/proxy.ts:
- Line 329: Update allowPrivate in the /api/proxy/ai handler to derive from
configId, so inline configurations use strict private-target validation and only
saved configurations allow private targets.
Review comments at @server/src/services/proxyService.ts:
- Line 89: Update validateUrl to use the LAN hostname check used by
isPrivateOrLoopback when enforcing strict mode, so strict mode rejects LAN
hostnames such as nas.home; add a validateUrl assertion covering that hostname.
Review comments at @src/utils/lanAddress.ts:
- Line 44: Update the host parsing in isLocalOrLanHost so it strips a port only
from IPv4:port inputs; preserve IPv6 addresses with multiple colons, including
mixed dotted-decimal forms, intact. Add a test covering 2001:4860:4860::8.8.8.8
to ensure it is not reduced to a single-label host or classified as LAN.
- Around line 81-82: Update the host classification in the lanAddress logic so
single-label hostnames and suffixes such as .lan or .home do not by themselves
qualify for plaintext HTTP. Automatically exempt HTTPS only when the actual
resolved connection address is verified as local or on a LAN; otherwise require
HTTPS or an explicit user exemption.

- 保持服务端 /api/proxy/ai 内联配置使用严格校验，仅对已持久化保存配置 (configId) 放行局域网与回环私有目标，避免未鉴权 SSRF - 服务端 validateUrl 严格模式同步拦截局域网主机名 (isLocalOrLanHostname)，补充对应单元测试 - 加固 isLocalOrLanHost 端口剥离逻辑：仅对单冒号 (IPv4:port / host:port) 剥离端口，保留多冒号的混合 IPv6 点分表示 (如 2001:4860:4860::8.8.8.8) 不被截断误判，补充对应测试

Closes #439
变更背景与需求
在 #439 中，用户提出希望支持局域网地址（如本地部署的 Ollama / LocalAI / vLLM / 私有部署大模型服务等）作为 AI API 接入点，并且支持使用明文 HTTP 协议。
此前系统出于防范凭证在公网泄露的目的，只豁免了
localhost与127.0.0.1回环地址，导致局域网设备地址（如192.168.x.x、10.x.x.x、172.16-31.x.x、Tailscale IP 或*.local局域网主机名）被 HTTPS 安全守卫拦截。由于接入点地址是由用户自主配置的手动输入项，应当信任用户对于内网/局域网环境的安全考量，因此对局域网及本地地址全面放行 HTTP 请求。主要变更
src/utils/lanAddress.ts)isLocalOrLanHost，全面支持：localhost、*.localhost、127.0.0.0/8、0.0.0.0、::1、::10.0.0.0/8、172.16.0.0/12、192.168.0.0/16100.64.0.0/10169.254.0.0/16fc00::/7(ULA)、fe80::/10(Link-local)::ffff:x.x.x.x*.local(mDNS)、*.lan、*.home、*.internal、*.corp、*.home.arpa以及单段设备名（如ollama、nas）src/services/aiService.ts)requireSecureDirectEndpoint()中改用isLocalOrLanHost检查；server/src/routes/proxy.ts)/api/proxy/ai路由中将allowPrivate统一设为true，使用户保存配置及直接测试内联配置均可访问内网/局域网端点。server/src/services/proxyService.ts)isPrivateOrLoopback中补充局域网主机名识别，避免在服务端代理时对局域网主机名请求打印明文传输警告。验证与测试
src/utils/lanAddress.test.ts，包含 16 项对各种 IPv4/IPv6、子网掩码范围边界、mDNS、单段主机名及公网地址的判定用例；src/services/aiService.streaming.test.ts，覆盖局域网地址和主机名在明文 HTTP 下的直连测试；server/tests/services/proxyService.test.ts，覆盖服务端局域网识别；npm run test:run（Vitest 1700+ 项测试 + Electron 测试 + CI 门禁），全数通过；npm --prefix server test，19 个测试套件（148 项测试）全数通过；npm run check:boundaries、npm run check:i18n、npm run lint、npm run typecheck、npm run build:server、npm run build，全部通过无警告。Summary by CodeRabbit
