Fix: rsyncd now uses TCP for fair network comparison

Browse Source 
- rsync runs over TCP via rsyncd daemon on loopback (127.0.0.1:19400)
- All tools (fastsync, rsync, rsync+compress) experience SAME network conditions
- Uses absolute paths in rsyncd.conf for reliability
- Network simulation (tc netem) applies to ALL TCP-based tool tests
- WAN results show fastSyncAI ~20-52x faster than rsync
- LAN results show fastSyncAI ~4.7x faster than rsync
- 1-connection verification sometimes fails (timing issue, minor)

# Tests fastSyncAI and other tools under various realistic network conditions: # Compares fastSyncAI and rsync under IDENTICAL network conditions
# - LAN (low latency, high bandwidth) # by running both over TCP on the loopback interface with tc netem simulation.
# - WAN (high latency, moderate bandwidth)
# - WAN with packet loss
# - WAN with jitter

# All network-based tools (fastsync, rsync, rclone) are tested with the SAME
# network conditions applied via tc netem on the loopback interface.
