notebooklm-mcp-cli-consolidated-tool-pattern

Upstream notebooklm-mcp-cli uses consolidated tools with action parameters (e.g., source_add with source_type=url/text/file/drive) rather than granular per-action tools. Upgrading from a custom 42-tool wrapper to upstream 38-tool design requires a full skill rewrite — tool names and call signatures change substantially. Plan for skill update as a mandatory deliverable in any notebooklm-mcp upgrade.
