Move proto defs to a dedicated repository managed as git subtree

continuing from the discord chat. It would be beneficial for downstream projects to be able to track changes to the protobuf definitions. The least painful way to manage this probably via a git subtree, the tl;dr is part of your git tree is copied to a different repo. It's still part of the current repo, it's still included in things like clones, it's just something that can be pushed to independently.

to initialize (assuming anki_proto is the repo name)

git remote add proto_remote https://github.com/ankitecks/anki_proto.git

to push

git subtree push --prefix=proto/ proto_remote main

then projects downstream can track this similarly.

if you initialize the repo, and the necessary token gh side (I just need the name of the secret not the actual secret), I can add a job to the release workflow to conditionally push on change

Start by reviewing the proto/ directory, the linked git subtree guide, and the repository's release workflow. Set up the dedicated repository and its GitHub-side secret as described, then verify that protobuf definitions can be pushed independently and that the release workflow conditionally pushes when proto/ changes.
