Path traversal in @mobilenext/mobile-mcp MCP server (CVE-2026-33989)

The @mobilenext/mobile-mcp server passed the `saveTo` and `output` parameters of its `mobile_save_screenshot` and `mobile_start_screen_recording` tools directly to filesystem operations without validation, allowing an attacker to write files outside the intended workspace. The issue was fixed in version 0.0.49.
