E01 - Getting started with Jan + hello world script

• Start Jan in `student-agent-pack/` and run basic startup checks.
• Take a look at the student-agent-pack, especially AGENTS.md, BOOTSTRAP.md, tools/, exercises/, and also opencode.json
• Run `python exercises/01/hello_world.py` and capture output.
• Edit the `TODO-STUDENT` in `exercises/01/hello_world.py` and rerun once.
• Verify one value manually from `exercises/01/data/tiny.csv`.

Inputs

• Install workflow
• OpenRouter key in .env
• exercises/01/hello_world.py + tiny.csv

Deliverable

startup evidence + one script run + one manual check + one TODO change note.
