<!-- markdownlint-disable MD041 --> Adds a new progress tracking and visualization package (`cli/internal/render/progress`) to provide user feedback during long-running operations like transfers. **Key components:** - **`progress.Tracker`** - Generic event tracker that consumes raw events from a channel, maps them to progress events, and forwards to a visualizer. Handles context cancellation automatically. - **`bar.barVisualizer`** - Terminal progress bar with scrolling log. Shows recent items with status icons (⏳ running, ✓ completed, ✗ failed) above a progress bar that updates in place. Displays error summary after completion. - **`simple.SimpleVisualizer`** - Minimal line-by-line output for non-interactive terminals or logging scenarios. - **Format utilities** - Tree-style error formatting and customizable item name formatters. - **Slog interception**: The default `slog` logger is replaced with a `bufferedHandler`, allowing the bar visualizer to drain the buffer on each render cycle and print log lines as permanent output above the animated progress bar. Once tracking is complete, the original logger is restored. - **Terminal detection**: automatic selection between bar (interactive) and simple (piped) visualizers. <!-- Usage: `Fixes #<issue number>`, or `Fixes (paste link of issue)`. --> Fixes: open-component-model/ocm-project#801 Signed-off-by: Piotr Janik <piotr.janik@sap.com> # Conflicts: # cli/go.mod # cli/go.sum # cli/integration/go.mod # cli/integration/go.sum
