message: "Loop appears to be infinite with no termination condition"

description: |
  while(true) or for(;;) without break/return creates infinite loops.
  Ensure there's an exit condition.

  ✅ FIX: Add break condition

  ```typescript
  while (running) {  // control flag
      if (shouldStop()) break;
  }
  ```
