livewire: Volt entfernt — Komponenten als Livewire-4-Single-File-Components, Route::livewire(), Livewire::test(); livewire/volt deinstalliert

- 83 Komponenten: Livewire\Volt\Component → Livewire\Component
- 73 Routen (admin, auth, customer): Volt::route() → Route::livewire()
- 88 Testdateien: Volt::test/actingAs → Livewire::test/actingAs
- VoltServiceProvider gelöscht; composer remove livewire/volt
- config/livewire.php auf v4-Schlüssel (component_layout, component_placeholder,
  component_locations, make_command: SFC ohne ⚡). Der alte Schlüssel layout war
  wirkungslos; alle gerouteten Komponenten setzen ihr Layout selbst.
- CLAUDE.md, AGENTS.md, boost.json, .cursorrules, Skill volt-development
- Roadmap: erledigt; Larastan erfasst SFCs weiterhin nicht (Blade-Dateien)

Suite 2.325 grün, einer übersprungen; Larastan und Pint ohne Meldung;
route:cache und view:cache laufen.
