Fix/overstable flight paths

+## [0.4.3] - 2026-04-25
+
+### Fixed
+- Overstable disc flight paths now show a realistic left-hooking finish instead of appearing to straighten out at the end. All flight paths also fly straighter for longer before curving.
+- CSV import and export now include all newer disc attributes: Secondary Color, Secondary Pattern, and Custom Flight Numbers (Glide, Turn, Fade). Previously these fields were silently dropped during import/export.
+- CSV export now includes the Vault name for each disc.
