v1.37.4 fixes a race condition in async replication's scheduler dispatch logic and introduces server-side resource guardrails for objects, collections, tenants, and shards. CI improvements enable multiarch PR builds on ARM runners.

Why it matters: Async replication users should test dispatch scheduling behavior after upgrading. Evaluate new resource guardrails in dev to confirm they match your usage patterns.
