Summary

Add a first step in swift-packages (gated to runner.environment == 'self-hosted') that kills any orphan xctest, swift-test, or swift-driver processes before checkout/build/test. SIGTERM, then SIGKILL holdouts.

Why

Grogu is a shared workstation — interactive Xcode use can leak processes that hold Mach services + ports, which then deadlock subsequent CI jobs. Develop run 25824607025 hung in SPM AgentCore for 34 min on exactly this pattern (6 xctest zombies aged 22–24h from prior interactive use). Single-runner serialization means any matching process at job-start is safely killable.

Test plan

Merge to develop, watch the next CI run.
Step logs zero processes when clean.
Step exits 0 even when no zombies exist.
No regression on github-hosted (runner.environment gate verified).

Closes #182
