Vault background refresh for mcp_oauth credentials now supported

AI Impact Summary

Vault now supports automatic, background refresh for mcp_oauth credentials, reducing the chance of service interruptions from expiring credentials. Applications will renew leases behind the scenes without restarts, improving reliability for Vault-based authentication. Make sure your Vault lease TTLs and mcp_oauth renewal logic align with this feature, and monitor renewal success/failure to catch misconfigurations. See the Authenticate with vaults guidance for integration specifics.
