📝 Walkthrough

Walkthrough

The PR removes import/export functionality from the add_app page by deleting the associated FloatingActionButton and its animation dependency, makes the progress indicator display conditional based on active search state, and reformats migration documentation with clearer step formatting and a modernized arrow symbol.

Changes

Add App Page Refactoring

Layer / File(s)	Summary
Remove import/export button and clean up imports lib/pages/add_app.dart	The import/export FloatingActionButton is removed from the confirmation screen; animations and import_export_page imports are deleted since they are no longer needed.
Conditionally render progress indicator lib/pages/add_app.dart	The SliverAppBar progress bar now only displays when actively searching or picking app sources, improving layout when no operation is in progress.

Documentation Updates

Layer / File(s)	Summary
Reformat migration instructions README.md	"On Obtainium" and "On Updatium" migration steps are reorganized into a clearer ordered list with the import/export arrow formatted as "→" instead of "->".

Code Review

This pull request updates the README.md to use arrow symbols instead of hyphens and greater-than signs. In add_app.dart, it removes unused imports, conditionally displays the AppAddingProgressBar in the SliverAppBar based on search and source selection states, and removes the Import/Export floating action button from the confirmation page. There are no review comments, so no additional feedback is provided.
