The previous implementation used �ody.split('&') which always
processed the entire request body and allocated a full array,
regardless of the parameter limit.
The new implementation:
- Counts '&' characters iteratively without array allocation
- Exits immediately when the limit is reached
- Handles edge case of empty/null body
- Reduces time complexity from O(n) worst-case always to O(min(n, limit))
This particularly improves resilience against malicious requests
with thousands of parameters attempting to exhaust server resources
