#196 Update build configuration and workflows for enhanced local
publishing and sample builds

- Add `mavenLocal()` to repository configuration in sample projects.
- Update dependencies to distinguish between `mcp.kotlin.client` and
`mcp.kotlin.server`.
- Include `JAVA_OPTS` for optimized memory usage in GitHub workflow.
- Enhance build workflow to include local publishing and build steps for
sample projects.
- Add package-lock.json for Kotlin JS/WASM Store
- Switch to SNAPSHOT versions by default

## Motivation and Context

#196 Samples MUST be validated as part of the build

## How Has This Been Tested?

```sh
./gradlew :kotlin-sdk-core:publishToMavenLocal
./gradlew :kotlin-sdk-client:publishToMavenLocal
./gradlew :kotlin-sdk-server:publishToMavenLocal
( cd ./samples/kotlin-mcp-client && ./../../gradlew clean build )
( cd ./samples/kotlin-mcp-server && ./../../gradlew clean build )
( cd ./samples/weather-stdio-server && ./../../gradlew clean build )
```

## Breaking Changes
