v3.0.1

• Fixed Android install statuses being decoded incorrectly. InstallStatusAndroid now uses Play Core's actual InstallStatus values. Previously a failed update was reported as installing, a canceled one as installed, and real installing/installed states as unknown. This affects both installStateStreamAndroid events and AppUpdateInfoAndroid.installStatus.
• Fixed startImmediateUpdateAndroid and startFlexibleUpdateAndroid hanging when Google Play doesn't start the update flow. They now throw a PlatformException with code UPDATE_NOT_STARTED when Play declines to start the flow, or START_UPDATE_FAILED when launching it throws (the message is in details). Previously the future never completed, every later start call failed with ALREADY_RUNNING, and a launch exception could crash the app.
• Moved the Android plugin package from tech.axions.in_app_update_flutter to me.pulkitagarwal.in_app_update_flutter. Flutter's generated plugin registration picks this up automatically; it only affects native Android code or ProGuard/R8 rules that reference InAppUpdateFlutterPlugin by its fully qualified name.
• Moved the repository, homepage and issue tracker to github.com/buildwithpulkit/in_app_update_flutter, and updated the author and license holder to Pulkit Agarwal.
• README: added an Error Handling section listing every Android and iOS error code and an InstallStateAndroid fields table, fixed the flexible update example (state.installStatus → state.status), and listed inAppUpdateFailed as a possible immediate update result.
