ShowOpenDialog.rs

1//! `nativeHost:showOpenDialog` handler. Wires VS Code's
2//! `nativeHostService.showOpenDialog(options)` contract to Tauri's
3//! dialog plugin.
4//!
5//! Contract:
6//!   - `properties: ["openDirectory" | "openFile" | "multiSelections" |
7//!     "createDirectory" | "showHiddenFiles"]`
8//!   - `filters: [{ name, extensions: ["vsix", …] }, …]`
9//!   - `title`, `buttonLabel`, `defaultPath`
10//!   - returns `{ canceled: bool, filePaths: string[] }`.
11//!
12//! The "Install from VSIX…" flow relies on `filters` to narrow the picker
13//! to `.vsix` and on `openFile + multiSelections` so the user can pick
14//! multiple archives at once.
