#302 Update samples build workflow (#330)

# #302 Update samples build workflow

- Introduce workflow to build samples independently from the main
project
- Keep building samples against the current snapshot version of the SDK.
Update composite build configuration.
- Temporarily disable "samples/kotlin-mcp-server": the multiplatform
project is broken. **It doesn't compile for me even on the main
branch**. Not working with [MCP
Instepcor](https://modelcontextprotocol.io/docs/tools/inspector),
because CORS is not configured. Deserves a separate PR to fix.

## Motivation and Context

Samples should be independently buildable
