Avoid instantiating `rich.text.Text` objects just to calculate string length in the `_safe_truncate` method. This method is called frequently during the TUI render loop for song properties (title, artist, genre), and bypassing the object creation provides a measurable performance boost.

💡 What: Optimized the
_safe_truncatemethod insrc/ui/tui.pyto use the built-inlen(text)instead of instantiating arich.text.Textobject exclusively to check the string length.🎯 Why: Creating Rich
Textobjects is comparatively expensive. Calling it inside a high-frequency rendering loop (where_safe_truncateis invoked multiple times for every visible song row to format titles, artists, and genres) created an unnecessary bottleneck. The built-inlen()serves the exact same purpose here since the strings are already cast and unstyled.📊 Impact: Reduces object instantiation overhead per TUI render cycle, specifically scaling with the number of visible rows. This keeps the application responsive as memory footprints stay lower during frequent updates (e.g., rapid scrolling).
🔬 Measurement: Execute
python -m src.mainand populate multiple songs. Rapidly navigating (scrolling up/down) will maintain higher responsiveness with lower CPU utilization due to the skipped allocations.PR created automatically by Jules for task 8815532809408457892 started by @omsingh02
