refactor: Split transport implementations into modules

Browse source 
Split the  transport implementations into dedicated modules to improve modularity
and reduce core dependencies.

Added shared test module for common test utilities.

Key changes:

- Create mcp-transport/mcp-webflux-sse-transport module
 - Move SseClientTransport → WebFluxSseClientTransport
 - Move SseServerTransport → WebFluxSseServerTransport
 - Move related tests and utilities

- Create mcp-transport/mcp-webmvc-sse-transport module
 - Add new WebMvcSseServerTransport implementation
 - Add corresponding tests and integration tests

- Add framework-independent SSE client implementations to core module
 - Add FlowSseClient using java.net.http
 - Add HttpClientSseClientTransport using java.net.http

- Keep StdioClientTransport/StdioServerTransport in core (no external deps)

- Create mcp-test module for shared test infrastructure
 - Move abstract test base classes
 - Move shared test utilities and mocks
 - Update test dependencies

The modular approach allows users to choose between:

- Framework-specific implementations (WebFlux/WebMVC)
- Pure Java implementations (java.net.http)
- Basic implementations (STDIO)
