test(promql): add PR-derived gaps to the process E2E matrix

[zzylol]

Summary

Extend the production-process ASAPQuery compatibility matrix with unsupported-but-accepted PromQL shapes found in the ASAPQuery PR audit. Each case is sent to the real backend binary and must fall back atomically to the Prometheus endpoint:

• avg_over_time, spatial count, spatial avg — ASAPQuery feat(query): maintain shared current-series quantile and TopK state #700 / backend feat(promql): compile and execute count/avg aggregation families from the ASAPQuery matrix #503
• raw-value topk — ASAPQuery test(clickhouse): measure automatically selected SUM and MAX plans #629/feat(query): maintain shared current-series quantile and TopK state #700 / backend Exact TopK (accuracy: Exact) has no warm-tier materialization -- always falls to archive #432
• vector/vector and vector/scalar arithmetic — ASAPQuery fix(query): dispatch Vector vs Matrix in asap_tier_result_to_query_result #256/Type physical plan references as summary definitions #572/feat: compose ClickHouse exact subtrees with summaries #577/Make completed summary windows immutable after durable flush #644 / Planner feat(control_plane): emit shard_count=12 (ASAP_SHARD_COUNT) to smooth edge flush #343 / backend feat(promql): execute binary arithmetic over warm summary readouts #504
• wider lookback over a materialized window — ASAPQuery feat(control-plane): require complete plan publication #466/Rotate retired physical series on catalog reactivation #640 / backend feat(control-plane): realize Planner window candidates and feed back costs #473

This is stacked on #505, which adds the #706 warm rows. As implementation PRs land, their rows should move from this fallback set into the warm instant/range set. Contributes to #501; it does not close the umbrella.
