* Embed stdlib in minijuvix library
We add a new step at the beginning of the pipeline called Setup that
registers the modules in the standard library with the Files effect. The
standard library is then used when the Scoper queries the Files effect
for modules as it resolves import statements.
Use of the standard library can be disabled using the global
`--no-stdlib` command-line option.
* CI: Checkout submodules recursively for stdlib
* Add a new `--no-stdlib` option to shell check
* Poke CI
* CI: Checkout submodules in the test job
* [WIP] EntryPoint now has options. --no-termination is a new global opt.
* Add TerminationChecking to the pipeline
* Add TerminationChecking to the pipeline
* Keep GlobalOptions in App
