## Steps to Reproduce
1. Create a new NativeScript project or use existing one
2. Run `ns build android`
3. Error occurs during plugin build phase

## Attempted Solutions (All Failed)
1. **Manual patching:** Created scripts to remove `package` attribute after prepare/build
2. **CLI hooks:** Tried `after-prepare` and `before-build` hooks
3. **Gradle patching:** Attempted to patch manifest during build process
4. **Upgrading:** Updated to latest NativeScript versions (8.9.x)
5. **Downgrading:** Downgraded to SDK 30, build tools 30.0.3, AGP 7.0.4
6. **Postinstall scripts:** Automated patching after npm install

### Relevant log output (if applicable)

## Root Cause Analysis
The issue is that the NativeScript core plugin generates the manifest dynamically during build, and there is no static source file in `node_modules` to patch. The manifest is regenerated after every prepare/build, making all local workarounds ineffective.

## Expected Behavior
The NativeScript core plugin should generate `AndroidManifest.xml` without the `package` attribute, or use the `namespace` attribute instead, to be compatible with newer AGP versions.

## Impact
This prevents building NativeScript projects with newer Android build tools, forcing developers to use outdated tooling or abandon NativeScript for Android development.

## Additional Notes
- The manifest is generated at: `platforms/tempPlugin/core/src/main/AndroidManifest.xml`
- No static source file exists in `node_modules/@nativescript/core/platforms/android/`
- This affects all NativeScript 8.x projects using newer Android build tools
