Greptile Summary

This PR adds ordered reader navigation and daily completion tracking for user-created recitation collections, including completion APIs, state providers, language propagation, and collection-row status UI.

• Adds personal-collection completion requests and Riverpod state management.
• Carries collection items and languages through adjacent reader navigation.
• Marks completion from reader lifecycle, swipe, and finish paths.
• Extends reader controls and routing for the new navigation source.

Confidence Score: 3/5

The PR should not merge until personal chants stop completing on mere display and adjacent items no longer inherit an unrelated chant's language.

Reader initialization currently records each newly displayed personal-collection chant, while adjacent navigation can resolve nullable-language items using the preceding item's language and display the wrong version.

Prompt To Fix All With AI

### Issue 1
lib/features/reader/presentation/screens/reader_screen.dart:132-136
**Reader Open Completes Chants**

When a user opens a personal-collection chant or swipes onto an adjacent one, reader initialization calls `completeCurrent`, causing the newly displayed chant to be recorded as complete before the user advances or finishes it.

### Issue 2
lib/features/reader/domain/services/navigation_service.dart:57
**Previous Language Leaks Forward**

When an adjacent personal-collection item has no language, this fallback assigns the previous item's language, causing the reader to resolve the destination chant in the wrong language instead of using the configured content-language behavior.

```suggestion
        language: adjacentText.language,
```
