# Wrapping `bazelisk build` in retry — not just dependency
# resolution, like the SPM jobs above — because Bazel resolves
# external repos lazily during the build itself. There's no
# equivalent to `swift package resolve` we could isolate; a
# transient HTTP failure (e.g. on a `rules_swift` transitive
# like `MobileNativeFoundation/index-import`) surfaces as a
# build failure. Bazel caches successful downloads, so a retry
# after a flake is cheap.
#
# Each command runs in a subshell so a `cd` for the example
# build doesn't leak its cwd change into subsequent retries.
