============================================================

📋 INFORMACIÓN GENERAL:
• Título: Phase 2: Implement Navigation BLoC for Devocionales Page
• Estado: open (Open/Closed)
• Autor: Copilot
• Creado: 2025-12-25 23:42:03
• Rama origen: copilot/refactor-devocionales-page-phase-2
• Rama destino: feature/new-chinese-language-zh

📝 DESCRIPCIÓN:
Implements Phase 2 of the Devocionales page refactoring by extracting navigation state management into a dedicated BLoC following the repository's established patterns.

## Changes

### Navigation BLoC Implementation
- **`DevocionalesNavigationBloc`**: Manages devotional index navigation with automatic boundary checking and SharedPreferences persistence
- **6 Events**: `NavigateToNext`, `NavigateToPrevious`, `NavigateToIndex`, `NavigateToFirstUnread`, `InitializeNavigation`, `UpdateTotalDevocionales`
- **3 States**: `NavigationInitial`, `NavigationReady` (with auto-calculated `canNavigateNext`/`canNavigatePrevious`), `NavigationError`

### Key Features
- Index clamping prevents out-of-bounds access
- Automatic calculation of navigation capabilities on every state change
- Static helper `findFirstUnreadDevocionalIndex(devocionales, readIds)` for UI layer
- Factory method `NavigationReady.calculate()` simplifies state creation

### Example Usage
```dart
// Initialize navigation
bloc.add(InitializeNavigation(initialIndex: 0, totalDevocionales: 100));

// Navigate with automatic boundary checking
bloc.add(NavigateToNext());  // No-op if at last devotional

// Jump to specific devotional
bloc.add(NavigateToIndex(42));

// UI responds to state changes
BlocBuilder<DevocionalesNavigationBloc, DevocionalesNavigationState>(
  builder: (context, state) {
    if (state is NavigationReady) {
      return Column(
        children: [
          Text('Devotional ${state.currentIndex + 1} of ${state.totalDevocionales}'),
          ElevatedButton(
            onPressed: state.canNavigateNext ? () => bloc.add(NavigateToNext()) : null,
            child: Text('Next'),
          ),
        ],
      );
    }
    return CircularProgressIndicator();
  },
)
```

### Testing
- 40 comprehensive tests covering initialization, navigation, edge cases, persistence, and full user flows
- All 1,247 existing tests remain passing

### P0 Tasks Completed
- `flutter analyze --fatal-infos`: No issues
- `dart format .`: Applied
- `dart fix --apply`: No fixes needed
- `flutter test`: All passing

### Dependencies
- Temporarily commented `coverde` due to `file` package version conflict between integration_test SDK and coverde's process dependency
