notebooklm-mcp-cli-auth-requires-two-files-not-one

Upstream notebooklm-mcp-cli stores auth in two files under $NOTEBOOKLM_MCP_CLI_PATH/profiles/default/: cookies.json (30+ cookies) and metadata.json. The legacy notebooklm-py used a single storage_state.json. Setting NOTEBOOKLM_MCP_CLI_PATH env var points the server at the config dir; cookies are loaded from profiles/default/cookies.json automatically on container start.
