Update code samples so tutorials build and run

[IanoNjuguna]

Discussed in #276

^{Originally posted by IanoNjuguna August 13, 2026}
Some of our tutorials and session notes need to be updated, i.e. commands that don't work, packages that no longer exist, and dead links.

Work will happen on the fix/tutorial-code-samples branch and ship as one PR.

Checklist: tutorials to verify

Go through each file, follow the steps like a new user would, and tick it off
when it works (or once it's fixed).
