docs: drop "firewall" terminology

 AI agents need to access APIs, databases, and internal tools — but permanent credentials are a security risk. qURL creates **time-limited, auditable access links** that automatically expire:
 
 - **Time-limited** — links expire after minutes, hours, or days
-- **IP-scoped** — firewall opens only for the requesting IP via NHP
+- **IP-scoped** — access is granted only to the requesting IP via NHP
 - **Auditable** — every access is logged with who, when, and from where
 - **Revocable** — kill access instantly if something goes wrong
