Pull request overview
This PR addresses a memory issue where HTTP/2 downloads could cause excessive RAM usage by buffering entire files when the read buffer size was artificially limited. The fix conditionally applies read buffer size limits only when bandwidth management is active.
Key Changes
- Disables HTTP/2 for downloads when bandwidth management is active to work around Qt buffering behavior
- Conditionalizes all
setReadBufferSize()calls to only execute when_bandwidthManageris present - Fixes typo "badnwidth" → "bandwidth" in error message
