Add two new optional skills:
- siyuan (optional-skills/productivity/): SiYuan Note knowledge base
API skill — search, read, create, and manage blocks/documents in a
self-hosted SiYuan instance via curl. Requires SIYUAN_TOKEN.
- scrapling (optional-skills/research/): Intelligent web scraping skill
using the Scrapling library — anti-bot fetching, Cloudflare bypass,
CSS/XPath selectors, spider framework for multi-page crawling.
Placed in optional-skills/ (not bundled) since both are niche tools
that require external dependencies.
