Fix crash when launched via hotkey - September 25, 2026

• Fix TypeError: Cannot read properties of undefined (reading 'replace') when the command is launched via a hotkey or deeplink without a typed number
• Fall back to the clipboard when no number is typed and no text is selected
• Use Raycast's built-in open instead of the open npm package, fixing an uncaught spawn open EAGAIN error
• Declare platforms: ["macOS"] and add Store keywords
• Keep only a single leading + when sanitizing the number (previously + anywhere in the input was kept)
