[Initiative] Namespaces

[juliuskrah]

Summary

Introduce namespaces to allow multiple teams, organisations, or enterprises to manage their own git repositories of catalogs and configs within the same platform without conflicts. #100 and #65 provides the foundations for this task.

Scope

In scope:

• Namespace isolation for repositories containing catalogs and configurations
• Namespace-scoped access control
• Userspace, organisation, and enterprise tiers

Out of scope:

• Cross-namespace sharing/federation (future)

Acceptance Criteria

• Repositories are fully isolated between namespaces
• Access control is enforced at the namespace boundary
• All three tiers (user/org/enterprise) are supported (think GitHub namespaces)
• Namespace creation and deletion are auditable

Tracking

• Milestone: TBD
• Labels: area/auth, priority/p2
