Sprint 1: Auth, metro map canvas, services, and retro UI

Authentication:
- Laravel Fortify + Sanctum with Inertia views
- RBAC middleware (admin, project_owner, team_member, viewer)
- Retro terminal-styled login/register/forgot-password pages

Metro Map (core UI):
- D3.js zoomable SVG canvas with metro line rendering
- Station nodes with glow-on-hover, status coloring, tooltips
- Breadcrumb navigation for multi-level drill-down
- Node preview panel with zoom-in action
- C64-style CLI bar with blinking cursor at bottom

Backend services:
- ProjectService (CRUD, phase transitions, park/stop, audit logging)
- ThemaService (CRUD with audit)
- MapDataService (strategy map L1, project map L2)
- Thin controllers: MapController, ProjectController, ThemaController
- 32 routes total (auth + app + API)

Style foundation:
- Retro-futurism theme: VT323, Press Start 2P, IBM Plex Mono fonts
- Dark palette with cyan/orange/green/purple neon accents
- Comprehensive seed data (4 themes, 12 projects, commitments, deps)
