📝 Walkthrough

Walkthrough

This PR implements a note duplication feature across the application. It adds UI elements for duplicating notes (menu items and bottom sheet actions), introduces model methods to copy and persist duplicated notes with updated metadata, and refactors navigation logic into a reusable extension function.

Changes

Cohort / File(s)	Summary
Core Duplication Logic app/src/main/java/com/philkes/notallyx/presentation/viewmodel/BaseNoteModel.kt	Added three public suspend/regular functions: duplicateNote(), duplicateNotes(), and duplicateSelectedBaseNotes(). These methods create note copies with new IDs, append "copy" suffix to titles, update timestamps, and persist via DAO. The selected-notes variant also closes action mode and displays a toast.
Navigation Refactoring app/src/main/java/com/philkes/notallyx/utils/AndroidExtensions.kt, app/src/main/java/com/philkes/notallyx/presentation/activity/note/EditNoteActivity.kt	Added openNote() Activity extension function to centralize navigation logic (routes to EditNoteActivity or EditListActivity based on note type, optionally clears back stack). Refactored EditNoteActivity to use this helper instead of manual Intent construction and conditional routing.
UI Action Integration app/src/main/java/com/philkes/notallyx/presentation/activity/main/MainActivity.kt, app/src/main/java/com/philkes/notallyx/presentation/view/note/action/MoreNoteBottomSheet.kt	Added duplicate menu item to MainActivity action mode for NOTES and ARCHIVED folders (content_copy icon). Extended MoreActions interface with duplicate() method and added corresponding action to bottom sheet. Both trigger duplication callbacks.
Note Editing app/src/main/java/com/philkes/notallyx/presentation/activity/note/EditActivity.kt	Added duplicate() override function that saves the current note, duplicates it via viewmodel, and navigates to the new note with back stack cleared. Imported openNote utility.
String Resources app/src/main/res/values/strings.xml	Added string resource duplicate and plurals resource duplicated_notes with singular/plural variants for UI labels and toast messages.
Translation Statistics TRANSLATIONS.md	Updated Coverage table entries from 326/326 to 328/328 for all languages, reflecting new string additions.

Poem

🐰 With whiskers twitched and ears held high,
I've added buttons, can't deny!
Duplicate notes with just a tap—
Copy, save, and close the gap! ✨

Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Out of Scope Changes check	❓ Inconclusive	The pull request introduces a potential concern: a duplicate method appears twice in EditActivity.kt, which may be an unintended duplication outside scope.	Verify whether the duplicate() method appearing twice in EditActivity.kt is intentional or an accidental duplication that should be removed.
