Breaking change: Customer Agent lead status contact property is now read-only

What it is

The hs_customer_agent_lead_status contact property is now system-managed and read-only. Only customer agent can write to it — API, integration, workflow and manual writes are refused.

Why it matters

External writes were polluting the field and skewing in-app reporting on customer agent's lead qualification. Locking it makes the property a reliable signal, and breaks anything currently writing to it.
