List all active TrueNAS alerts with severity levels.
AI agents call list_alerts to retrieve information from Truenas Ws without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns alert information without creating, modifying, deleting, or executing any operations. It is purely informational, making it a Read category tool with low severity since alerts are metadata about system state rather than sensitive operational data.
