Add create-book standalone plugin

[sapanparikh18]

Summary

• New standalone plugin that analyzes source code and produces a comprehensive technical book with an Astro website
• Originally created as a bee command, extracted into its own plugin since it has zero dependency on bee's workflow (no state tracking, agents, skills, or triage)
• Serves a different audience (anyone documenting a codebase) with its own 7-phase workflow

What it does

/create-book:create-book <source-dir> runs:

1. Exploration — Parallel agents analyze each subsystem
2. Audience & Positioning — Define the core thesis
3. Structure — Organize into parts/chapters, get approval, scaffold Astro site
4. Writing — Narrative prose with pseudocode and mermaid diagrams
5. Editorial Review — Review agents evaluate quality
6. Revision — Apply feedback in one pass
7. Source Code Audit — Ensure no verbatim code

Output

• book/docs/ — Markdown chapters (300-800 lines each, "Apply This" patterns)
• book/web/ — Astro website with dark/light theme, mermaid diagram zoom, chapter navigation

Plugin structure

create-book/
  .claude-plugin/plugin.json
  commands/create-book.md
  templates/              # Astro site boilerplate
  CLAUDE.md

Test plan

• Install plugin: claude --plugin-dir create-book/
• Run /create-book:create-book on a small codebase
• Verify prompt is displayed and fine-tuning question appears
• Verify book/docs/ and book/web/ are created after outline approval
• Verify cd book/web && bun run dev serves the site
