Cognee (build 48)

0.1.6: separate LLM/embedding config, two-store sync, generic docs

- Split configureLlm into LLM and embedding actions
- configureLlm now syncs to Cognee settings API (no restart needed)
- New Configure Embeddings action: separate API key, provider, model, endpoint, dimensions
- main.ts reads both LLM and embedding config from store.json
- Embedding config no longer hardcoded — user can change model, dimensions, endpoint
- store.json expanded with embeddingApiKey/embeddingProvider/embeddingModel/embeddingEndpoint/embeddingDimensions
- instructions.md rewritten for public release — removed custom pipeline references, added embedding setup docs
- Two-store problem solved: StartOS is source of truth via env vars at startup + settings API sync at runtime
