feat: add Streamable HTTP transport support for remote MCP providers (#358)
* feat: add Streamable HTTP transport support for remote MCP providers (#357)

Add `streamable_http` as a supported transport type for `MCPProvider`,
enabling connections to MCP servers that use the Streamable HTTP protocol
(e.g. Tavily remote endpoints). Previously only SSE transport was supported,
causing silent 5-minute timeouts when connecting to incompatible endpoints.

- Expand `MCPProvider.provider_type` to `Literal["sse", "streamable_http"]`
  (default remains `"sse"` for backwards compatibility)
- Route `streamable_http` providers through `streamablehttp_client` from
  the MCP SDK in `MCPIOService._get_or_create_session()`
- Handle variable-length context manager results from MCP transport clients
- Add `DataDesigner.list_mcp_tool_names()` for discovering available tools
- Update CLI form builder and controller to support the new transport option
- Add tests for streamable_http config, session creation, and form builder
