1//! Wire method: `nativeHost:pickFolderAndOpen`, `:pickFileAndOpen`,
2//! `:pickFileFolderAndOpen`, `:pickWorkspaceAndOpen`.
3//!
4//! Atom I1 (2026-04-21): before webview reload, mutate
5//! ApplicationState.Workspace and fire `$deltaWorkspaceFolders` to Cocoon so
6//! extensions see the folder arrive synchronously.
