ci-build reaches ~700 MB and is rewritten every job, on the machine that is also the mac-local runner for both app repos, so indexing it lands in the merge path for everything. mds_stores and mdworker_shared sit at the top of CPU while no build process is near it, which is why the load looked unexplainable.

Measured, same from-scratch build twice:

	peak load	mds trailing after build
output indexed	128	minutes
output excluded	12.5	stops

The marker is written by the job rather than committed, because the directory it belongs in is created by the build and removed between runs.

The stable caches outside the repo were excluded on the host itself (DerivedData, Android SDK, the runner's builds directory, Gradle home - 11 GB between them). Verified honoured with an mdimport probe.

Android gets the same treatment for its module build dirs.
