chore(examples): add examples
This commit adds examples to the jco, some of which are/will be referenced from the component-model book (https://component-model.bytecodealliance.org/).
I'm going to assume that the failing test is unrelated, considering none of the actually important code changed. Possibly a problem with ubuntu latest?
Yes, just a flake.
Hey @guybedford this is finally ready for review -- example CI is working properly
[EDIT] I'm also fine not committing the per-project WASM binaries -- so I could take those out... Would lighten the repo a bit
Sorry for the delay, thanks for the detailed review -- I was able to hit everything!
