feat: Phase 1 foundation - core infrastructure and navigation

Clean Architecture structure: - core/config - Environment configuration - core/theme - Material 3 theming with FlexColorScheme - core/error - Typed exception hierarchy - core/api - Dio HTTP clients with interceptors - core/auth - Authentication state management - routing - go_router with shell navigation - shared/layouts - Adaptive scaffold Dependencies added: - flutter_riverpod, riverpod_annotation, riverpod_generator - freezed, freezed_annotation, json_serializable - dio, go_router, shared_preferences - flex_color_scheme, flutter_adaptive_scaffold Features: - Responsive navigation (rail on desktop, bottom on mobile) - Dashboard placeholder with welcome card - Theme switching infrastructure - API client ready for Core API and Tatlock API 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
