Rate Limit Utilization Warnings

What: Rate limit warnings now show exact utilization percentages and use intelligent thresholds based on both token usage and time remaining.

How it appears:

75% of 5-hour limit used · resets in 2h
50% of weekly limit used · resets in 3d

Details:

  • Shows percentage of limit used instead of generic "Approaching limit" messages
  • Smart thresholds: warns at 75%/60%, 50%/35%, 25%/15% (tokens/time) for weekly limits
  • 5-hour limits now show warnings (previously silent)
  • Considers usage rate vs. time remaining in window
  • Evidence: Function N49() at line 467497, threshold config at j$3/S$3 line 467531
