refactor(Common): Remove deprecated Effect and Transport layer modules

The `Effect` module in Library.rs and the transport implementation modules (gRPC, IPC, WASM, Registry, Metrics, Retry, CircuitBreaker) in Transport/mod.rs—along with their DTO subcomponents (UnifiedRequest, UnifiedResponse, TransportError)—have been deprecated as the architecture migrates away from this transport abstraction.

Keep only the core modules (Environment, Error) and the Common transport interface. The DTO module retains only the Correlation submodule for now.

This cleanup removes dead code following the architectural shift to the new IPC and telemetry patterns.
