Clean and well-executed rename from tenants to organizations. Verified:

• All organization_id fields added to the correct Create/List messages with correct field numbers across agents, secrets, and llm protos.
• tenant_id fields properly removed from ziti_management messages with correct reserved declarations (separate statements for field numbers and names).
• tenants/v1/tenants.proto deleted; organizations/v1/organizations.proto created with matching structure and field numbers.
• Comment-only updates in chat and authorization protos are accurate.
• buf.yaml breaking change suppressions correctly scoped.
• No stale tenant references remain outside of reserved declarations and buf config.

LGTM.
