feat(core): implement Git repository operations with gRPC services

- Add advertise_refs functionality for Git protocol communication - Implement archive service with TAR/ZIP format support and streaming - Create blame service for Git file annotation with line tracking - Add branch management including create, delete, rename and compare operations - Implement merge checking with conflict detection and fast-forward handling - Add cherry-pick functionality for applying commits between branches - Integrate gix library for Git repository operations and object handling - Add comprehensive test suite covering all Git operations - Implement proper error handling and repository validation - Add pagination support for large result sets - Create protobuf definitions for all Git operations and data structures - Add build system for gRPC code generation and dependency management
