v0.37.4 -- Stability fixes from production log review¶

Metric view YAML "aterialization" truncation -- Fixed sanitizeMetricViewYaml() where an incorrect .slice(1).search(/^\S/m) pattern truncated the first character of "materialization:" instead of removing the invalid block. The same off-by-one bug in the measures section is also fixed.
Dashboard MISSING_GROUP_BY at runtime -- Added a static GROUP BY lint to dashboard validation that catches SQL mixing aggregate functions with non-aggregated columns before the EXPLAIN round-trip. Both pipeline and ad-hoc dashboard engines now reject these queries early. Strengthened the dashboard prompt and shared SQL rules with an explicit CROSS JOIN + aggregate GROUP BY requirement.
LLM fallback rotating to expensive models -- buildEndpointPool() now accepts an optional tier hint and uses getFallbacksForTier() to prefer same-tier endpoints before falling back to the full model pool. This prevents cheap classification tasks (e.g. flash-lite) from rotating to expensive reasoning models (e.g. claude-opus) on 429 exhaustion.

Gradual circuit breaker cooldown -- The rate limiter now decrements consecutive429s by 1 on success instead of resetting to 0, preventing rapid oscillation between blocked and unblocked states under sustained load.
Metric view repair prompt for materialization -- The LLM repair prompt now includes explicit guidance for materialization block errors: either include a complete materialized_views: list with name and type fields, or remove the block entirely.
