Add shared Meaning primitive and pure interpretation helpers for interval, tyre age, and championship gap columns on the live tower, tyre deg panel, and championship hub. Thresholds are exported consts (undercut window tied to PIT_LOSS_SECONDS from #13). Co-authored-by: Cursor <cursoragent@cursor.com>
