Subject: [PATCH] fix(fallback): merge new provider failure threshold fields in
 profile

The mergeProviderProfile function was missing the three new fields
added to PROVIDER_PROFILES (providerFailureThreshold, providerFailureWindowMs,
providerCooldownMs). This caused tests to fail because the profile
returned by getRuntimeProviderProfile did not include these fields.
