refactor: clean up tests/ root — delete junk, sort into subdirs

Deleted (7 files):
- test_discovery.py, test_windsurf_integration.py (trivial assert True stubs)
- pytest_simple.ini (unused --collect-only config)
- conftest_path.py (duplicate of conftest.py path setup)
- conftest_fixtures.py, conftest_full.py (unused conftest variants)

Moved to integration/ (6 files):
- test_blockchain_final.py, test_blockchain_nodes.py, test_blockchain_simple.py
- test_basic_integration.py, test_integration_simple.py, test_working_integration.py

Moved to fixtures/:
- mock_blockchain_node.py

tests/ root now has only conftest.py and README.md.

+     GOSSIP_BROADCAST_URL=http://127.0.0.1:7070/gossip
+
+2. Start a gossip relay service:
+   python -m aitbc_chain.gossip.relay --port 7070
+
+3. Configure P2P discovery:
+   - Add peer list to configuration
+   - Ensure ports are accessible between nodes
+
+4. For production deployment:
+   - Use Redis as gossip backend
+   - Configure proper network addresses
+   - Set up peer discovery mechanism
+
+Current status: Nodes are running independently with memory backend.
+They work correctly but don't share blocks or transactions.
