refactor: move presentation/game files to proper domain layers

Reorganize architecture by moving files from presentation/game to appropriate domain layers:

- Move static UI data (ascii_digits, ascii_rank_titles, rank_colors, rank_messages) to domain/models/ui/
- Move models (SessionState, SessionConfig, SessionAction, GameMode, StageConfig, ProcessingOptions, InputResult, CodeContext) to domain/models/session/, domain/models/stage/, domain/models/typing/
- Move loading steps to domain/models/loading/
- Move services (typing_core, text_processor, context_loader) to domain/services/
- Move presentation events to domain/events/presentation_events.rs
- Remove duplicate definitions in presentation/game/session_manager.rs and stage_repository.rs
- Update all import paths in src/ and tests/ to reflect new structure
- Fix all type mismatches and visibility issues

This change establishes proper layering:
- domain/models: Pure data models without business logic
- domain/services: Business logic and services
- domain/events: Domain and presentation events
- presentation/: UI layer only (screens, views, CLI)

All tests passing: 1419 passed, 0 failed
