fix: add curl connect-timeout and max-time to prevent hangs on Windows

The binary download and checksums download curl calls had no timeout
options, causing them to hang indefinitely if a connection stalled.
This was most visible on Windows GitHub Actions runners where the
CI job ran for 3 hours before being killed.

Add --connect-timeout 15 --max-time 120 to the binary download and
--connect-timeout 15 --max-time 60 to the checksums download so the
retry loop can cycle and eventually fail with a clear error instead
of hanging forever.
