Fix Docker Swarm discovery network name mismatch

- Changed NetworkName from 'chorus_default' to 'chorus_net'
- This matches the actual network 'CHORUS_chorus_net' (service prefix added automatically)
- Fixes discovered_count:0 issue - now successfully discovering all 25 agents
- Updated IMPLEMENTATION-SUMMARY with deployment status

Result: All 25 CHORUS agents now discovered successfully via Docker Swarm API
