Add --target alias support and configurable generation options

This PR enhances the make:action command by introducing a configurable --target alias system, along with optional CLI overrides for:

• --target
• --method
• --path
• --namespace

---

✨ What’s New

1. Target aliases (config-driven)

Reusable generation targets can now be defined in config/make-action.php:

'targets' => [
    'billing' => [
        'path' => base_path('plugins/Billing/src/Actions'),
        'namespace' => 'Plugins\\Billing\\Actions',
        'method' => 'execute',
    ],
],

Usage:

php artisan make:action CreateInvoiceAction --target=billing

This avoids repeatedly typing deep nested paths, especially in monorepo setups.

---

2. Deterministic precedence

Resolution order:

1. CLI options (--path, --namespace, --method)
2. Target alias config
3. Default config

CLI overrides always take priority.

---

3. Safer behavior

• The command fails if the file already exists (no --force support).

• Clear error messages for:

  • Unknown target aliases
  • Invalid method names

• Default behavior remains unchanged.

---

🧪 Test Coverage

Includes coverage for:

• Default generation
• Target alias usage
• CLI override precedence
• Custom path + namespace overrides
• Existing file failure
• Unknown target failure
• Invalid method failure
• Class name normalization

---

✅ Backward Compatibility

No breaking changes.
Default usage works exactly as before.
