feat(project-manager): integrate NotebookLM into discover and brainstorm v1.1

Add NotebookLM (Gemini 2.5 RAG) as primary internal knowledge source for
/discover and /brainstorm skills, complementing existing Dify KB datasets.

- /discover: NotebookLM as first source in Fase 1 (Pesquisa Interna)
- /brainstorm: NotebookLM Passo A before Dify KB Passo B in Fase 2
- datasets.json: dual-source structure (notebooklm + dify_kb)
- plugin.json: bump to v1.1.0, update description
- 7 notebooks mapped to topics for intelligent routing
