fix(install.sh/update.sh): Homebrew 升级免确认并显式按 formula 升级

- Homebrew 7 默认进入 ask 模式，升级或安装带依赖时会停下等待 [y/n]。
  用户运行脚本（以及 install.sh 中逐项确认后）已构成授权，统一加
  HOMEBREW_NO_ASK=1；用环境变量而非 --yes，旧版 Homebrew 不会因未知
  参数报错。
- update.sh 的 formula 升级显式加 --formula：kotlin-lsp 来自
  jetbrains/utils tap，不加时 brew 会把短名当成 cask，报
  “Cask 'kotlin-lsp' is not installed” 而升级失败。
