feat(backend): add RoleSet JSON types and missing OrganizationJSON fields

[jacekradko]

The backend SDK was missing types for the BAPI /v1/role_sets endpoints and several documented fields on OrganizationJSON, forcing consumers to write local augmentations. This adds them, matching the public BAPI OpenAPI schema (2021-02-05, surfaced through 2024-10-01 and 2025-11-10).

New: RoleSetJSON, RoleSetItemJSON, RoleSetMigrationJSON, plus the corresponding ObjectType entries. Added to OrganizationJSON: role_set_key, last_active_at, missing_member_with_elevated_permissions. All additive — no breaking changes.

📝 Walkthrough

Walkthrough

This PR adds JSON type definitions for role set resources to the Clerk backend package. Three new ObjectType constants (RoleSet, RoleSetItem, RoleSetMigration) are registered, accompanied by corresponding JSON interface definitions describing their payload shapes. These types are re-exported from the package root to expose them in the public API. The OrganizationJSON type is also extended with three new optional fields: role_set_key, last_active_at, and missing_member_with_elevated_permissions. A changeset documents the patch-level release.
