Environment variables for functions, sites, and projects can now be created, listed, retrieved, updated, and deleted programmatically through the Appwrite Server SDKs. Two new API key scopes, `project.read` and `project.write`, control access to the project-scoped endpoints, alongside the existing `functions.*` and `sites.*` scopes for resource-scoped variables.

This enables configuration as code, one-place rotation of secrets shared across multiple resources, and repeatable bootstraps of new environments and tenants from scripts or templates.
