Expose persisted agents to Agents API

[chubes4]

Summary

• Registers durable Data Machine agent rows as runtime WP_Agent definitions so bundle-installed brain agents are discoverable through Agents API.
• Maps Data Machine numeric access grants to Agents API agent slugs at the access-store boundary.
• Adds smoke coverage for persisted agent projection and access-store slug/ID translation.
