Suggestions

It would be cool if we can set up autotransform to automatically make suggestions on PRs/provide functionality for setting up schemas to run against PRs.

So, because Github doesn't let you suggest outside of right around the lines touched, the way we'll do this is by allowing AutoTransform to submit a PR against a human-authored branch.

So, I've been thinking about how AutoTransform might interact with human authored PRs. I'm thinking about the whole flow looking like this:

• Step 0: We come up with some transforms that look at stuff like dead code, formating, whatever. These get put in a JSON file.
• Step 1: I create my cool PR that does some cool thing.
• Step 1.5: I optionally add the autotransform:auto-apply label
• Step 2: I request autotransform as a reviewer.
• Step 3: This request triggers a Github Action that causes AutoTransform to check out my branch and run the transformations against it.
• Step 4a: If there are no changes that the transforms would do, AutoTransform comments on the PR saying it found no changes and removes itself as a reviewer.
• Step 4b: If the label autotransform:auto-apply is present, AutoTransform commits the changes directly to the branch, pushes them, and removes itself as a reviewer.
• Step 4c: Otherwise, AutoTransform sets up a separate branch, commits the changes to that branch, submits as a PR against my branch, requests me as a reviewer of that PR, then removes itself as a reviewer from my PR.
• Step 5: If a PR was created, I take a look at AutoTransform's PR, and merge it in to my branch if I like it. Otherwise I can reject it/take some of it/whatever.

We could do opt-in vs opt-out configuration, as well as automatically running against PRs vs needing to be added as a reviewer.
