notebooklm-upstream-streamable-http-sse-format

The upstream notebooklm-mcp-cli uses streamable-http transport (SSE format) rather than plain JSON REST. Direct curl to the /tools endpoint returns SSE event stream, not a JSON array. Tool enumeration requires either the nlm CLI inside the container (nlm tools list) or parsing the MCP initialize/list-tools protocol handshake — not a simple GET request.
