• Open files
• Unit tests (Path assemble logic from FileExplorer was decoupled from UI allowing us to have unit tests)
• Feature integration test

[Copilot]

Pull request overview

Adds an “open file” capability to the File Explorer by wiring a new Tauri command and decoupling path construction into a reusable utility, with accompanying unit and integration tests.

Changes:

• Introduces pathUtils helpers for assembling folder/file paths and adds unit tests for the path assembly logic.
• Updates FileExplorer to open files on double-click via a new Tauri open_file command.
• Extends the Tauri backend with a file command module and adjusts directory listing behavior; updates dependency range/lockfiles.

• path.file_stem() is used for all entries, including directories. For folder names containing dots (e.g., my.folder), file_stem will truncate the name to my and treat folder as an extension, which will make the UI show an incorrect folder name. Consider using file_name() when metadata.is_dir() is true (or always use file_name() and only compute extension for files).

        let name = path.file_stem()
            .map(|n| n.to_string_lossy().into_owned())
            .unwrap_or_else(|| "Unknown".to_string());

        let extension = path.extension()
            .map(|e| e.to_string_lossy().into_owned())
            .unwrap_or_default();
