Adapt Pinscope to DeepSeek, auto datasheets, and a shared library.
Based on manvalan/pinscope main. Default LLM is DeepSeek with local skills and PDF ingest. Datasheets are fetched from LCSC/TI, stored in the component library, and review extracts abs-max with a deeper checklist. Adds scripts/update-pinscope.sh for the production host.
