oteldb-ch: same binary without --embedded, serving all three query APIs from chstorage on a dedicated clickhouse-oteldb server (isolated footprint). Wired into the ingest fan-out (vmagent remote-write, otelcol logs+traces) and systems.yml with a per-system volume override for footprint accounting.

--only (or BENCH_ONLY): restrict a run to a subset of engines, bringing up just those plus the lane's ingest driver and querying/collecting/reporting only them — a fast feedback loop (e.g. --only oteldb,oteldb-ch for a head-to- head of the embedded vs ClickHouse storage).
