- Rename iosApp.xcodeproj → honeyDue.xcodeproj
- Rename Casera schemes → HoneyDue, HoneyDueExtension, HoneyDueUITests
- Split bundle IDs per-config: Debug=com.tt.honeyDue.dev, Release=com.tt.honeyDue
- Split app groups per-config: Debug=group.com.tt.honeyDue.dev, Release=group.com.tt.honeyDue
- Fix com.t-t. typo → com.tt. in test bundle IDs
- Add APP_GROUP_IDENTIFIER build setting with variable substitution in entitlements
- Replace all hardcoded app group strings in Swift with Info.plist runtime reads
- Remove stale PRODUCT_BUNDLE_IDENTIFIER from Config.xcconfig
- Update test plan container references
