Subject: Move summaries to markdown files for easier editing

- Extract summaries from books.json to summaries/{id}.md files
- Update app.js to fetch summaries dynamically from markdown
- Remove summary/summarySource fields from books.json
- Update AGENTS.md and CLAUDE.md documentation
- Add file:// protocol warning (must use HTTP server)
