Resolve GitHub sync conflicts

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Asks the builder to resolve the merge conflicts left by a pull from GitHub.

Call this after Pull changes from GitHub reports a merge conflict. Base44 runs a builder turn over the conflicted files, and one more automatic attempt if publishing the resolution finds that GitHub has moved on. The turn consumes credits like any other builder work. The response comes back only when the run ends, which can take minutes.

Resolution always lands on the repository's default branch.
