v4.0: Full Interactive Mode + 29-Agent Audited

🚀 v4.0 — The Complete Package

29 autonomous AI agents audited, fixed, and enhanced this script across 6 rounds.

🎮 NEW: Interactive Mode Selection

Run without -Mode and get a beautiful 4-option menu:

• [1] THROUGHPUT — max bandwidth (autotuning=experimental, cubic, LSO/RSC ON)
• [2] LOW LATENCY — min ping (Nagle OFF, ctcp, LSO/RSC OFF, MMCSS=0)
• [3] BALANCED — compromise (adaptive, cubic, Nagle OFF)
• [4] FULL MAX — throughput + telemetry OFF + Cloudflare DNS + ALL adapters

No more .bat launcher needed — the script is fully self-contained!
