flutter_libphonenumber_android

• Fix Android build failure Could not find method kotlin() on AGP 9 hosts where android.builtInKotlin=false — the state Flutter 3.44's migrator writes into every app's gradle.properties (#101, #102 — thanks @proninyaroslav for the diagnosis and initial fix).
• The Kotlin Gradle Plugin is now applied whenever AGP has not registered its built-in kotlin extension, instead of keying off the AGP version. This is correct on AGP 8 (KGP applied as before), AGP 9 with the built-in Kotlin opt-out (KGP applied), AGP 9/10 with built-in Kotlin active (KGP skipped; jvmTarget follows compileOptions.targetCompatibility), and is immune to stale android.builtInKotlin=false flags once AGP 10 removes the opt-out.
• The kotlin { compilerOptions { jvmTarget } } block now only runs when the external Kotlin Gradle Plugin is actually applied.
• Build script is now AGP 9 new-DSL-safe: removed the redundant Kotlin sourceSets entry and switched to =-style assignments.
• Note: Flutter 3.44 still prints "Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP): flutter_libphonenumber_android". This remains a false positive of Flutter's textual build-script scan and is unavoidable while this plugin supports Flutter <3.44. The plugin does not apply KGP on hosts where built-in Kotlin is active.

• Ready for Flutter's Built-in Kotlin cutover: the Kotlin Gradle Plugin is now applied conditionally — only on AGP <9, where the host's Flutter does not manage Kotlin itself — following the official Flutter migration guide for plugin authors. Flutter versions older than 3.44 remain supported.
• Note: Flutter 3.44 may still print "Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP): flutter_libphonenumber_android". This is a false positive: Flutter's detection is a textual scan that cannot see the AGP version conditional. The plugin no longer applies KGP on hosts where Built-in Kotlin is available, so it will keep building after Flutter's cutover.
• Example app: migrate off the Kotlin Gradle Plugin and bump Java/Kotlin compatibility to 17 (building the example now requires Flutter 3.44+; the plugin itself is unaffected).

• Reduce repeated work in getAllSupportedRegions: cache the digit regex used for masking, reuse a single PhoneNumberUtil instance, and format each example number once (#100 @higorlapacw)
