copilot-swe-agent[bot]andmonkeyWie 2daa9c45df Fix non-range download bug: downloaded bytes exceeding total file size ...

When HTTP server doesn't return Content-Length or doesn't support Range
requests, the download can accumulate extra bytes on pause/resume because:
1. Each retry/resume re-downloads from the beginning but writes at the
   accumulated offset
2. No size limit enforcement for non-range downloads
3. onDownloadComplete incorrectly uses chunk.remain() for non-range
   downloads, which gives negative values for chunk(0,0)

Fixes:
- Reset chunk state in downloadChunkOnce and runConnectionFallback for
  non-range downloads since server will send from beginning
- Add size limit checks in download loops when Size is known
- Fix onDownloadComplete to use conn.Completed for non-range downloads
  instead of unreliable chunk.remain()
- Add test cases for non-range download, pause/resume, and size limit
