Deploy to TestFlight

1. •Check for uncommitted changes — warn the user and do not proceed until the working tree is clean
2. •Bump the build number — read CURRENT_PROJECT_VERSION from Yiana/Yiana.xcodeproj/project.pbxproj, increment by 1, and replace all 6 occurrences in the file
3. •Commit the bump — stage the pbxproj and commit with message: Bump build number to N for TestFlight deployment
4. •Build the iOS archive — run:
   code

   xcodebuild archive -project Yiana/Yiana.xcodeproj -scheme Yiana -destination 'generic/platform=iOS' -archivePath /tmp/Yiana.xcarchive
   

   If the build fails, show the errors and stop.
5. •Export and upload — run:
   code

   xcodebuild -exportArchive -archivePath /tmp/Yiana.xcarchive.xcarchive -exportOptionsPlist Yiana/ExportOptions.plist -exportPath /tmp/YianaExport
   

   This automatically uploads to App Store Connect (destination=upload in the plist).
6. •Report result — show success or failure. On success, remind the user to check App Store Connect for processing status.
7. •Do NOT push to git automatically — ask the user if they want to push the build number bump.
