This commit adds support for Server-Sent Events (SSE) transport for MCP servers. - Updates `HttpServerConfig` to include an optional `transport` field, defaulting to 'http'. - Updates `connectToServer` to use `SSEClientTransport` when `transport` is set to 'sse'. - Uses `@modelcontextprotocol/sdk/client/sse.js` for SSE transport. - Adds test coverage for the new configuration option.

This commit introduces support for the SSE (Server-Sent Events) transport protocol in mcp-cli. - **Config**: Added `SseServerConfig` interface. SSE servers must be explicitly configured with `"type": "sse"`. - **Client**: Added `createSseTransport` which automatically appends `/sse` to the URL if not present, adhering to common conventions for SSE endpoints. - **Client**: Updated `connectToServer` to route connections to the appropriate transport (SSE, HTTP, or Stdio) based on the configuration. - **Tests**: Added unit tests for the new configuration type and type guards. This aligns the implementation with the provided design document, ensuring backward compatibility for existing HTTP server configurations.

- Updated `README.md` to include a new "SSE Transport (Legacy)" section. - Added configuration examples for enabling SSE transport with `"type": "sse"`. - Included a deprecation note advising users to prefer Streamable HTTP transport for new servers.

Shouldn't this work with streamable http? |

The mcp server I'm using doesn't support streamable http unfortunately. The only way I got it to work was to use SSE. |
