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