- Introduced a new sample project `TransparentProxySample` demonstrating the use of a transparent MCP proxy that connects to both a backend MCP server and an interceptor server. - Implemented `McpInterceptorGateway` to handle requests through interceptor chains before forwarding to the backend server. - Added `InterceptorChainRunner` to manage the execution of interceptor phases. - Enhanced `McpInterceptorGateway` with configuration options for backend and interceptor clients. - Created unit tests for the `McpInterceptorGateway` to validate capabilities, interceptor invocation, and payload mutation. - Updated project references and dependencies in the test project.

- Removed the old `InterceptorChainExecutorTests` and migrated tests to `InterceptorChainOrchestratorTests`. - Introduced `InterceptorChainOrchestrator` to handle client-side chain execution with proper ordering of mutations, validations, and sinks. - Updated test cases to validate the new orchestrator's behavior, ensuring correct execution order and handling of various scenarios including error cases. - Enhanced the ability to filter interceptors by event and phase during execution. - Added comprehensive tests for validation summaries and error handling in both mutation and validation phases.
- Replaced all instances of InterceptorEvents with InterceptionEvents across the codebase. - Updated method calls and event checks in the InterceptingMcpClient, GatewayProxyConfigurator, and other related classes to reflect the new event naming. - Removed the old InterceptorEvents class to streamline the event handling process. - Adjusted tests to ensure compatibility with the new event structure.

Re-implementation of C# interceptors SDK with clearer focus on server-side / gateway interceptors.
Fixes a lot of issues with the existing implementation.
Still more boilerplate than I'm happy with, but this is better than what was there. Will refine further in later PRs.
