v3.4.8

What's New

• Fix: eliminate persistent macOS Keychain password prompts when switching accounts in Sync mode. Keychain reads/writes now go through /usr/bin/security (Apple-signed tool already in the CLI's partition list), preserving Claude Code CLI access without triggering "Always Allow" dialogs.
• Fix: Independent-mode tokens (user:profile only) are now properly filtered from the Sync-mode account list, preventing scope mismatch issues.
• Improvement: mode switching forces a fresh credential read instead of using potentially stale managed backup.

中文

• 修复：消除同步模式下切换账号时反复弹出的 macOS 钥匙串密码提示。Keychain 读写改为通过 /usr/bin/security（Apple 签名工具，已在 CLI 的 partition list 中），不再触发"始终允许"对话框，也不影响 Claude Code CLI 的访问权限。
• 修复：独立模式的 token（仅 user:profile 权限）现在会从同步模式账号列表中正确过滤，防止权限范围不匹配。
• 改进：切换模式时强制重新读取凭证，避免使用过期的备份数据。
