Pull request overview

This PR implements progress tracking for the cslol-manager migration feature, allowing users to see real-time updates during both the packaging and installation phases of mod migration. The implementation adds a new MigrationProgress type that tracks the current phase (packaging or installing), progress counters, and the current file being processed.

Changes:

• Added progress tracking types and event emission for migration operations
• Created a new useMigrationProgress hook that listens to both migration and install progress events
• Converted migration commands to async to support non-blocking operations with progress updates

• Progress is emitted before checking if the folder exists. If a folder doesn't exist (line 108-110), the progress will still show it as being processed, which may be misleading to users. While this maintains the counter accuracy (showing X out of total selected), it could confuse users who see a folder name in the progress that wasn't actually packaged. Consider moving the progress emission after the folder existence check, or updating the current file name only for folders that are actually processed.

    for (i, folder) in folders.iter().enumerate() {
        let _ = app_handle.emit(
            "migration-progress",
            MigrationProgress {
                phase: MigrationPhase::Packaging,
                current: i + 1,
                total,
                current_file: folder.clone(),
            },
        );

        let mod_dir = installed_dir.join(folder);
        if !mod_dir.is_dir() {
            tracing::warn!("Skipping missing folder: {}", folder);
            continue;
