Understand Bazel builds and cache behavior

Bazel projects now show completed builds and tests alongside the build systems already supported by Tuist. Each invocation includes its command, targets, result, duration, processor time, action counts, package counts, and metadata reported by Bazel.

The new cache view connects action-cache and content-cache requests to the invocation that produced them. It shows hit rates, transfer volume, latency, throughput, action names, target labels, and individual request outcomes.

Existing Bazel projects receive these views automatically after configuring Tuist as their build event and remote cache service.
