v0.2.10 - Windows PowerShell output visibility fix

Fixed

• Windows PowerShell output visibility: Child process output (Figma scan details, code generation progress) now displays correctly on Windows
  • Root cause: spawnSync with shell: true spawned cmd.exe as intermediary, which interfered with console output and ANSI color codes
  • Solution: Call Node.js scripts directly via process.execPath with argument arrays instead of shell command strings
  • Eliminates shell quoting/escaping issues and works identically across all platforms
