- Added progress bar to `get_all_existing_rules` for better user feedback during parallel fetch.
- Removed duplicate `render_progress_bar` definition in `main.py`.
- Added test case `test_get_all_existing_rules_shows_progress`.
- Created `.jules/palette.md` for journal entries.

+## 2024-05-23 - CLI Progress Bars in Parallel Operations
+**Learning:** Adding visual feedback (progress bars) to parallel operations (like `ThreadPoolExecutor`) requires careful management of `stderr`. Standard logging (`logging.warning`) can interfere with `\r` carriage returns used for progress bars.
+**Action:** Always clear the line (`\r\033[K`) before logging warnings inside a progress-tracked loop, and redraw the progress bar afterwards if necessary.
