ci(065): D1 readiness waits for full tool catalog before scoring

The retrieval scorer was running against a partially-indexed instance: the
readiness probe passed at the first indexed tool (>=1 search result), so scoring
started before all 7 reference servers connected -> Recall@5 measured 0.387 vs
baseline threshold 0.631 (false regression).

Fix: poll /api/v1/tools until the catalog reaches the near-full count (~45 tools
across the 7 servers) and add a short settle for the index build, then score.

Verified locally end-to-end on a fully-indexed instance: Recall@1/3/5/10 =
0.418/0.560/0.681/0.791, Gate(recall_at_5) PASS (0.681 vs 0.631) — the baseline
is exactly reproducible. actionlint clean.
