notebooklm-mcp-cli-auth-two-file-profile-format

Upstream notebooklm-mcp-cli v0.5.17 expects auth in two separate files: $NOTEBOOKLM_MCP_CLI_PATH/profiles/default/cookies.json (raw cookie dict with cookies key) and profiles/default/metadata.json. The legacy notebooklm-py used a single storage_state.json. CSRF token and session ID fields in cookies.json can be left empty — upstream auto-extracts them on first API call. Set NOTEBOOKLM_MCP_CLI_PATH=/config pointing to the bind-mounted config directory.
