Description

there are some places in fetch.js that malloc memory.i think it need some works to do like library_fs.js to support >2GB (may use "CAN_ADDRESS_2GB" macro )

Contributor guide

Research direction
Identify all malloc calls in fetch.js and check if they use the CAN ADDRESS 2GB macro or similar bounds checks. Trace the memory allocation paths to ensure compatibility with >2GB environments.
