This commit introduces a major refactoring of the MCP Java SDK to implement a session-based architecture
for server-side implementations. The changes improve the SDK's ability to handle multiple concurrent
client connections and provide an API better aligned with the MCP specification.
Key changes:
- Introduce McpServerTransportProvider interface to manage client connections
- Rename ClientMcpTransport to McpClientTransport and ServerMcpTransport to McpServerTransport
- Add exchange objects (McpAsyncServerExchange, McpSyncServerExchange) for client interaction
- Update handler signatures to include exchange parameter: (args) -> result to (exchange, args) -> result
- Rename Registration classes to Specification classes
- Update method names (e.g., rootsChangeConsumers to rootsChangeHandlers)
- Deprecate old interfaces and classes for removal in 0.9.0
- Add migration guide (migration-0.8.0.md)
Resolves#9, #15
