disable-model-invocation	true

Create a new chapter for the Jupyter Book. The user provides a chapter number and topic title.

Steps:

1. Determine the directory name following the convention: book/NN_topic_name/ (e.g., book/15_moons/)
2. Create the chapter directory under book/
3. Create the main markdown file inside it (e.g., book/15_moons/moons.md) using the structure of existing chapters as a template, including:
   • A top-level heading with the chapter title
   • Placeholder sections for key content
   • Proper MyST Markdown syntax
   • Use of the project's custom LaTeX macros where relevant (\Msun, \Rearth, \Mjup, \kB, \dv, \pdv, etc.)
4. Create a figures/ subdirectory inside the chapter directory
5. Add the chapter to book/_toc.yml in the correct position (ordered by chapter number)
6. Report what was created
