In doing this, I improved some of the comments/assertions on the consumer interface that became apparent when implementing the example. I found some bugs by hand while testing and proptest also found the same bugs.

I forgot that we have a container type for the success+failure bounds, so use that here.
So that we can use this logic in `git-branchless-submit`, which wants to be fundamentally aware of commit stacks as part of submitting.
So that we can call e.g. `Repo::create_branch` and ignore the error if the branch already exists.
It was previously assumed that all forges would want to create and operate on branches, and, in fact, the calling `git-branchless-submit` code would even create the branches returned by `CreateStatus`. This has turned out not to be the case. For example, the Phabricator forge embeds the commit identifier in the (updated) commit message, and doesn't need a branch (and, in practice, it's turned out to be more annoying than useful to create the branches as shorthand identifiers). This commit removes the auto-branch-creation behavior and updates the terminology to be branch-agnostic and refer to "commits" instead of "branches". As a result, commits are now "submitted" at the beginning of their submission lifecycle, and future pushes (etc.) are "updates". This doesn't exactly make sense with the name of the `--create` flag, since we never refer to "creating" a commit anywhere, only "submitting" one, so we might want to change that flag name or terminology in the future.
Not used now, but might be used in the future to generate local-friendly branch names for the Github forge.
I noticed that relative timestamps were enabled in the cloned repo's smartlog. That kind of output is non-deterministic, so it can't go into snapshot tests. To fix this, invoke the same configuration that we do to initialize repositories normally.
