//! # Workspace Effect (CreateEffectForRequest)
//!
//! Effect constructors for workspace-level RPC methods. Handles:
//! - `applyEdit` and `showTextDocument` via round-trip to Sky through
//!   `UserInterfaceProvider::SendUserInterfaceRequest` (resolves when Sky has
//!   actually applied the edit or shown the document).
//! - `Workspace.RequestResourceTrust` and `Workspace.IsResourceTrusted` return
//!   a permissive `true` heuristic so `vscode.git` proceeds; single- window dev
//!   runtime stays trust-by-default.
//! - `$updateWorkspaceFolders` applies workspace folder additions/removals to
//!   `ApplicationState.Workspace` and broadcasts the delta.
