List all vendors with their icon counts.
AI agents call list_vendors to retrieve information from Tech Icons without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays static information about vendors and their icon inventory. It does not create, modify, delete, or execute any operations. This is a straightforward read/query operation with minimal risk.
