GHSA-3p2m-h2v6-g9mx: @mobilenext/mobile-mcp alllows arbitrary file write via Path Traversal in mobile screen capture tools

The @mobilenext/mobile-mcp package has a path traversal vulnerability (a security flaw where an attacker can write files outside the intended directory by using special path characters like `../`) in its `mobile_save_screenshot` and `mobile_start_screen_recording` tools. The `saveTo` and `output` parameters are passed directly to file-writing functions without checking if the paths are valid, allowing an attacker to write files anywhere on the system.
