[1.x] Refactor and expand generator commands

[JasperTey]

Added

• ddd:list to show a summary of current domains in the domain folder.
• Additional generator commands that extend Laravel's generators and funnel the generated objects into the domain layer:
  • ddd:cast {domain}:{name}
  • ddd:channel {domain}:{name}
  • ddd:command {domain}:{name}
  • ddd:enum {domain}:{name} (Laravel 11 only)
  • ddd:event {domain}:{name}
  • ddd:exception {domain}:{name}
  • ddd:job {domain}:{name}
  • ddd:listener {domain}:{name}
  • ddd:mail {domain}:{name}
  • ddd:notification {domain}:{name}
  • ddd:observer {domain}:{name}
  • ddd:policy {domain}:{name}
  • ddd:provider {domain}:{name}
  • ddd:resource {domain}:{name}
  • ddd:rule {domain}:{name}
  • ddd:scope {domain}:{name}

Changed

• BREAKING: ddd:* commands no longer receive a dedicated domain argument (e.g., ddd:action Invoicing CreateInvoice). The domain is instead specified in two ways:
  • As an option: ddd:action CreateInvoice --domain=Invoicing (this will take precedence).
  • Shorthand prefix within the name: ddd:action Invoicing:CreateInvoice.
