The Longest Quiet Stretch

The classroom noise meter logs every minute. The teacher wants to brag: how long did the quiet last? 🤫

You get the noise levels and the quiet limit. Print the length of the longest run of consecutive minutes strictly below the limit.

Example:

Input: levels = [3, 1, 2, 8, 1, 1, 1, 9], limit = 4 Output: 3

The streak of minutes below 4 builds up as 1, 2, 3 (indices 0-2), resets at the loud 8, then builds again to 1, 2, 3 (indices 4-6), resetting at 9 — the longest streak reached is 3.
