Refactor GitLab MCP server implementation

- Removed gitlab-index.js and integrated its functionality into index.js.
- Updated server name to "gitlab-mcp-server" and version to "1.1.0".
- Enhanced GitLab API client with methods for creating, merging, retrieving, and closing merge requests.
- Added tools for handling merge requests with detailed input validation using Zod.
- Implemented command-line argument parsing for transport mode (stdio or http) and port configuration.
- Introduced Streamable HTTP transport for remote access and debugging.
- Updated package dependencies to the latest versions.
