feat: fix macOS permissions and improve CLI commands

  - Fix macOS "operation not permitted" errors (Setsid → Setpgid)
  - Simplify 'loex list' output (remove service details from main view)
  - Add individual service start: 'loex start \[project\] \[service\]'
  - Move detect to subcommand: 'loex config detect \[project\]'
  - Enhance detect to skip existing services and show current configuration
  - Improve overall CLI usability and command structure

+Loex automatically detects common project types and suggests appropriate commands when using the `config detect` or `config wizard` commands.
 
 **💡 Important**: Run the command from your project's root directory to enable auto-detection. Loex analyzes files in the current directory to suggest the best commands for each service type.
