fix: #145 仪表盘版本缓存 + #144 macOS手动安装检测 + #146 更新提示持久化 + #148 AI助手Web模式CORS

- dashboard.js: 版本/状态信息持久化缓存，实例切换时自动清空 (#145)
- service.rs: macOS is_cli_installed 改为真实路径探测，无plist时返回默认Gateway条目 (#144)
- utils.rs: 新增 common_non_windows_cli_candidates，resolve_openclaw_cli_path 优先检测 standalone/手动安装路径 (#144)
- config.rs: macOS get_local_version 增加 resolve_cli + canonicalize，detect_installed_source 增加 CLI 分类 + standalone 检测 (#144)
- dev-api.js: macOS CLI/版本/来源检测补齐 Intel Homebrew + standalone + findOpenclawBin (#144)
- main.js: 更新 banner dismiss 从 sessionStorage 改 localStorage (#146)
- assistant.js: Web 模式 AI 测试走后端代理 api.testModel 绕过 CORS (#148)
