v25.12.1

• Added enterprise SCIM coverage with new data sources (users, user, groups, group). Provider registration lives in provider.go, with implementations under data_source_github_enterprise_scim_users.go and related files.
• Delivered enterprise team management: resources and data sources for teams, memberships, and organization links, documented in enterprise_team.html.markdown and sibling docs.
• Unified enterprise cost center management by folding resource assignments into resource_github_enterprise_cost_center.go; authoritative users, organizations, and repositories arguments now replace the deprecated helper resource.

Breaking

• Removed the standalone github_enterprise_cost_center_resources resource (code, tests, docs). Migrate configurations to the embedded assignments on github_enterprise_cost_center; see enterprise_cost_center.html.markdown.

Enhancements

• Cost center assignments now batch, retry, and use context-aware CRUD (resource_github_enterprise_cost_center.go).
• Enterprise team resources/data sources include plan-time validation and leverage the go-github enterprise SDK (data_source_github_enterprise_team.go).

Docs & Examples

• New SCIM and enterprise team documentation under website/docs/{d,r}/enterprise_*.
