SFTP upload broken on macOS 27

Problem

After updating my Mac to macOS 27, Tabby's built-in SFTP file transfer no longer works. The same SSH connection itself still establishes successfully in the terminal, but the SFTP functionality fails. Prior to the macOS update, both SSH and SFTP worked normally.

To Reproduce

1. Open Tabby on macOS 27.
2. Connect to a remote server via SSH (SFTP is enabled on the server).
3. Open the SFTP panel -> attempt to upload file using built-in SFTP.
4. Observe that SFTP does not start upload

Environment

• Tabby version: 1.0.235
• OS: macOS 27
• SFTP connection method: Built-in Tabby SFTP panel
• Third-party plugins: Disabled
