Android template generates invalid Kotlin in $$androidCxxLibName$$Package.kt

[qalqi]

Describe the bug

The Android template generates an invalid Kotlin file for $$androidCxxLibName$$Package.kt.

The file has a .kt extension but mixes Java and Kotlin syntax, causing the generated project to fail compilation.

To Reproduce

1. Generate a new Nitro module using create-nitro-module.
2. Build the Android project.
3. The generated $$androidCxxLibName$$Package.kt fails to compile.

Generated code:

package com.$$androidNamespace$$;

import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.module.model.ReactModuleInfoProvider;
import com.facebook.react.BaseReactPackage;
import com.margelo.nitro.$$androidNamespace$$.$$androidCxxLibName$$OnLoad;

public class $$androidCxxLibName$$Package : BaseReactPackage() {
  override fun getModule(name: String, reactContext: ReactApplicationContext): NativeModule? = null

  override fun getReactModuleInfoProvider(): ReactModuleInfoProvider =
    ReactModuleInfoProvider { emptyMap() }

  companion object {
    init {
      $$androidCxxLibName$$OnLoad.initializeNative();
    }
  }
}

Expected behavior

The template should generate valid Kotlin.

For example:

package com.$$androidNamespace$$

import com.facebook.react.BaseReactPackage
import com.facebook.react.bridge.NativeModule
import com.facebook.react.bridge.ReactApplicationContext
import com.facebook.react.module.model.ReactModuleInfoProvider
import com.margelo.nitro.$$androidNamespace$$.$$androidCxxLibName$$OnLoad

class $$androidCxxLibName$$Package : BaseReactPackage() {
  override fun getModule(
    name: String,
    reactContext: ReactApplicationContext,
  ): NativeModule? = null

  override fun getReactModuleInfoProvider(): ReactModuleInfoProvider =
    ReactModuleInfoProvider { emptyMap() }

  companion object {
    init {
      $$androidCxxLibName$$OnLoad.initializeNative()
    }
  }
}

Additional context

The generated template appears to mix Java and Kotlin syntax:

• public class is Java syntax and is invalid in Kotlin.
• The file is emitted with a .kt extension.
• Semicolons are acceptable in Kotlin, but the class declaration is not.

This looks like a template generation issue rather than a Kotlin compiler issue.
