fix(download): automatically degrade to single connection when server rejects chunked range bounds
When a server (like fuckingfast.co) ignores the upper bound of a range request (returning bytes=start-end/total), aria2 aborts with 'Invalid range header'. This patch treats that error as transient and mutates the download payload to force connections=1 before re-enqueuing. This ensures aria2 issues an open-ended range request (bytes=start-) on the retry, seamlessly resuming the download.
