…cs, wire circuit-breaker telemetry - Add supabase/functions/_shared/regions.ts as the canonical source for SUPPORTED_REGIONS, per-region env-var resolution, and region detection. - Refactor regional-router, regional-auth/auth-utils, regional-health-check, and consistency-validators to import from the shared module, eliminating seven duplicated region-list declarations and two separate url/key lookup tables. - Reconcile the router's broader country-code mapping (NZ/HK for ap-southeast) into the single source of truth. - Convert syncUserProfileAcrossRegions() from sequential for...of to concurrent Promise.allSettled, bounded by the slowest region rather than the sum of all regions. Include per-region duration in the return value and propagate it through sign-up.ts audit logging. - Update docs/webhook-dead-letter-queue.md to describe the implemented automatic retry schedule (1m/2m/4m/8m/16m/32m ±10% jitter), circuit-breaker thresholds (5 failures → 1-hour pause), and DLQAutoRecovery config surface. - Add injectable onCircuitStateChange callback to DLQRecoveryConfig and wire it into _circuitFor()'s onStateChange handler for ops-dashboard integration. - Add unit tests for concurrent sync bounding and injected circuit-breaker telemetry.
