//! E2E tests for workspace resource lifecycle.
//!
//! Covers:
//! - Workspace CRUD
//! - Provider creation scoped to a workspace
//! - Workspace isolation (resources in one workspace are invisible in another)
//! - `--all-workspaces` listing
//! - Deletion guard (workspace cannot be deleted while resources exist)
//! - Successful deletion after resource cleanup
