CVE-2024-24750: fetch(url) leads to a memory leak in undici

The vulnerability stems from improper backpressure handling in stream implementations. The commit diff shows critical changes:- In fetchFinale(): Replaced 'start' with 'pull' and added backpressure check (controller.desiredSize)- Added queuing strategies with explicit highWaterMark- Modified stream initialization in httpNetworkFetch. The original 'start' implementation's infinite read loop (while(true)) would continuously buffer data regardless of consumer readiness, matching the described memory leak scenario when body isn't consumed. The functions directly implement the streaming logic that failed to respect backpressure, making them clearly vulnerable.
