Walkthrough

Refactors main navigation to ViewPager2 with a new FragmentStateAdapter, replaces fragment transactions with pager-based switching, updates layout to include ViewPager2, and disables swipe. Integrates Firebase Remote Config using resource defaults to trigger a non-cancelable update dialog and opens Play Store via an intent when required.

Changes

Cohort / File(s)	Summary
Main activity refactor app/src/main/java/com/runnect/runnect/presentation/MainActivity.kt	Replaces manual fragment transactions with ViewPager2 navigation; initializes and controls vp_main via MainPager; maps bottom nav selections to pager indices; removes Timber logs; updates remote config fetching using REMOTE_CONFIG_FETCH_INTERVAL_SECONDS and string resources; shows update dialog and opens Play Store via Intent.ACTION_VIEW.
ViewPager2 adapter app/.../presentation/MainPager.kt	Adds MainPager FragmentStateAdapter with 4 pages: CourseMain, StorageMain, Discover, MyPage; caches created fragments; exposes item count and createFragment.
Layout update app/src/main/res/layout/activity_main.xml	Replaces FrameLayout (fl_main) with ViewPager2 (vp_main), constrained between parent top and bottom navigation.
String resources app/src/main/res/values/strings.xml	Adds update_dialog_title, update_dialog_message, update_dialog_btn_text, and default_version for remote config defaults and dialog text.

Poem

A pager hops from tab to tab—so fleet!
Four cozy burrows, fragments neat.
A carrot-colored prompt: “Update, please!”
Remote winds whisper version keys.
With one quick leap to the store I go,
Thump-thump—new trails for Runnect’s flow! 🥕🐇
