docs: add runtime plugins and DSL chapters, reorganize README

- Add chapters 14 (Runtime Plugins) and 15 (Building DSLs) to book
- Update wiki workflow to deploy new chapters and fix their internal links
- Move Quick Start section to top of README for better discoverability
- Add comprehensive Zyn Book navigation with all 15 chapters
- Replace old Quick Start with Development Setup section
