* Nightly workflow

* Refactored TempProject into its own module and started on tests

* Created test projects with a diamond-graph
This will allow us to test the update tool in all expected situations
- One dependency added/removed
- One dependency updated
- Transitive dependencies changed

It's also a nice addition for testing any other commands as well.

* Added to primary-registry
Metadata and zipped up

* Built the update subcommand.

* Lockfiles need to be written!

* Fixed misspelling of dependency_changes

* Reverted test_registry arg back to invisible

* Changed target_packages to package_specs
Clarity?

* Downgrading was added as a concept

* Added lockfile method to view packages as packageIds

* Installs the new packages now, forgor.

* No longer throws if missing lockfile
It will generate a new one instead based on the
manifest.

* Clarity on the filtering process for try_to_use

* Added needed imports
-- they got stashed by accident

* Made the clippy happy and fixed grammar mistakes

* Delete root from registry
They're not packages to be consumed.

* Add new tests, almost done with them all so far.

* Added the rest of snapshots missing

* Testing now works, yay!

* Deleted testing code by mistake and forgot snap
They say to run your tests before push..
This is why.

* Appleasing the formatter
Import in the wrong order...
Extra newline at the end...

* Made it look... *pretty* and cleaned messes

* another blood sarciface for rust fmt

* Doing final cleanups per comments upstream

* The gods demand it, another formatter sacrifice

* The coolness must be toned down.

* A little silly mistake indeed
Seemingly forgot to filter out packages to update for try_to_use.
instead it kept them and got rid of everything else.
