Add three-species interop stress test
Runs Rust, Go, and Python organisms simultaneously on one mesh. 4 tests in 42 seconds: 1. Three-way peer discovery: all species find each other via gossip 2. Challenge broadcast: Go and Python both receive challenge S-expressions 3. Solution broadcast: non-Rust species receive solution messages 4. Peer status exchange: Go processes probe peer-status Tests the core whitepaper claim: any language with an S-expression parser can join the mesh. Not in CI — run manually from repo root: ./tests/three_species_test.sh Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# three_species_test.sh — Stress test for Rust/Go/Python mesh interop
3+
#
4+
# Runs all three species simultaneously on one mesh and verifies they
5+
# discover each other, share challenges, and exchange solutions.
6+
#
7+
# Tests the core whitepaper claim: any language with an S-expression
8+
# parser can join the mesh.
9+
#
10+
# Prerequisites: cargo, go, python3, nc (netcat)
11+
# Run from repo root: ./tests/three_species_test.sh
12+
# Not in CI — requires three network services running simultaneously.
