Robust Local Git State

Sync behaves weirdly sometimes, even though test coverage is pretty good.

I wonder whether it can be because we sometimes get outdated responses from github, and react immediately to them (e.g. by reverting what was just done locally).

I think we should refactor the entire sync logic to exactly mirror how git would behave, except for our custom auto-merge strategies to resolve conflicts. Everything outside single-file conflicts should be equivalent to git, and well tested to follow that spec.
Maybe there's even a library giving us git in JS.

it seems that our sync failures got completely resolved by #78. I ranked this down to medium-value, does no longer seem essential to a working app, but would be nice to be more like git, more robust, more well-tested
