`GET /v1/warm-pools/{configId}/workspaces`

Returns the most recent pre-warmed workspaces for a warm pool config, including their status (warming, snapshotting, ready, assigned, expired, failed). Useful for inspecting why a pool is not delivering ready workspaces. Returns up to 10 entries. To watch warm-hook output live during the `warming` phase, subscribe to [GET /v1/warm-pool-workspaces/{workspaceId}/stream](#tag/Environments/operation/streamWarmPoolWorkspace).
