EXPB kept the payload server's SSE connection open while stopping Nethermind. Stop K6, the payload server, and Alloy before shutting down the execution client, while preserving log capture and profiler finalization. An ARM smoke run reduced post-workload cleanup from about 65.6 seconds to 5.7 seconds and retained normal Nethermind shutdown.

Add an optional, validated EXPB_SKIP_OVERRIDE for corpora containing entries older than the available snapshot state. This allows callers to align the first payload with the snapshot without changing the runner's source configuration or suppressing runtime exceptions. Defaults are unchanged.

Validation: 53 unit tests passed (6 integration tests deselected), Ruff passed, and an ARM live teardown check passed with 1,000 payloads and no exceptions or invalid blocks. Full sequential-workflow calibration on both architectures is in progress.
