`list_industries`read-only	List the industries LeadQuasar covers and how many verified businesses each holds. Use this first when unsure what industry wording will match.
`search_businesses`read-only	Return a sample of matching businesses with industry, location and data-quality signals. Contact details (name, company, email, phone, address) are never returned by this tool — it shows what exists and how reachable it is, not who to call.
