Skip building the engine in release builds if the CaH has not changed

Note that in our current configuration, we run 2 builds concurrently. If git_ref^ is in progress, this logic is flawed.

We should reduce the concurrent builds to 1 to make this sound.

Flutter LUCI Recipes

This repository contains Flutter's LUCI recipes. For the LUCI infrastructure config, see flutter/infra. Builds can be found in the Flutter Dashboard.

Supported repositories roll their .ci.yaml into flutter/infra, which updates what properties builds have. For example, flutter config specifies various dependencies the different tests require, which are then used by the flutter_deps recipe_module No modifications to flutter/infra are required to work on the recipes.
