Prepend CARGO_BUILD_JOBS=max(2, floor(cpus/4)) to every agent launch command so concurrent fleet runs don't oversubscribe the host when child cargo builds fan out. Harmless on non-Rust agents — cargo is the only consumer of the env var. Tests previously hardcoded CARGO_BUILD_JOBS=8 (passed only on 32-CPU hosts); they now compute the expected value from os.cpus() so CI on any CPU count stays green.
