xtaci/kcptun v20251205

on GitHub

1. Adjusted probe test interval(IKCP_PROBE_INIT) from 7s to 500ms.
   This will mitigate stall status in the one-way downloading scenario.
   Eg: In previous release, Sink(download simulation) stucks for 7 seconds sometimes , due to this probe issue.
2. Fixed '--ratelimit' command line parameter in server.(json not affected).
