v2.0.0 — Profile-aware Astro book scaffold

Major version bump — profile-aware architecture.

What's new

BOOK_PROFILE env var now dispatches schemas, integrations, and recipes across three profiles:

• academic — KaTeX (36-macro library), BibTeX pipeline, 10 academic callouts + Theorem family, 7-state status frontmatter
• tools — 8 callouts, volatility + T1-T4 source tiers, convergence dashboard
• minimal — single-author manifesto / essay collection (uses tools schema)

Plus, profile-agnostic:

• Three-tier Tufte layout (65/80/90ch) + left chapter-nav sidebar
• Pre-flight content validator catches bibkey/XRef/Figure typos before they ship
• Cloudflare Workers + Static Assets deploy via wrangler.toml
• 11 terse-pointer recipes + 2 chapter-shape templates
• Dual license (MIT for code, CC-BY-4.0 for content)

Reference implementations

• Academic profile: ~/Claude/post_transformers/guides/web/ deployed at https://post-transformers-guide.brandon-m-behring.workers.dev
• Tools profile: ~/Claude/book-template-astro/ (Agentic Coding: Principles and Practices)

Migration

v2.0 is for new books only. Existing books freeze on current code; v3.0 (npm package, deferred) will migrate them.
