Scaffold the course repo and author the full curriculum in dependency-chain order, following the settled build decisions in handoff.md. - Scaffold: course README, vendor-neutral AGENTS.md (dogfoods Module 5), _TEMPLATE.md (the fixed 9-section module shape), root .gitignore, ship config. - Modules 1-2: reference exemplars (locked for tone/depth/lab style). - Modules 3-27: full lessons + runnable labs, each following the template, respecting the chain, vendor/model-agnostic, with "feel the pain" labs. - Module 8 hosting comparison web-researched and date-stamped (as of 2026-06-22), not written from memory; expansion-zone modules carry Verify-before-publish. - Capstone: the full loop end to end on the running tasks-app example. Lab code syntax-checked (Python/shell/YAML); every module has the 7 core template sections.

Title: done command crashes on an empty list
When I run python cli.py done 0 right after a fresh checkout — before adding any tasks — it throws
an IndexError and dumps a stack trace instead of a friendly message. Every other command handles the
empty-list case fine, so this one feels like an oversight.
Steps to reproduce:
- Delete tasks.json (or clone fresh).
- Run
python cli.py done 0. - See the traceback.
Expected: a clear message like "no task at index 0", exit non-zero, no traceback.
Environment: Python 3.12, macOS.
