Added __init__.py files to directories with Python files that were
missing them to fix imports and pytest discovery:
- apps/agent-coordinator/src/app and subdirectories (auth, monitoring, protocols, routing)
- apps/coordinator-api/src/app/agent_identity, reputation, utils
- apps/wallet/src/app/keystore, crypto, receipts
- apps/pool-hub/src/poolhub/services
- Test directories for agent-coordinator, blockchain-node, coordinator-api, pool-hub, wallet
- Source directories for agent-services and ai-engine
- blockchain-node subdirectories (contracts, economics, network, rpc)
- Migration directories for blockchain-node, coordinator-api, pool-hub
This improves import reliability and reduces the need for sys.path
manipulation in conftest.py.
- Replace all 2,087 uses of datetime.utcnow() across 294 files
- Add UTC import to datetime statements where needed
- Addresses Python 3.12+ deprecation warning (report item #3)
- Add sys import to 29 test files across agent-coordinator, blockchain-event-bridge, blockchain-node, and coordinator-api
- Remove apps/blockchain-event-bridge/tests/test_integration.py (obsolete bridge integration tests)
- Remove apps/coordinator-api/tests/test_integration.py (obsolete API integration tests)
- Implement GPU registration in marketplace_gpu.py with GPURegistry model persistence
chore(gitignore): add development log file patterns
- Add patterns for .log, .out, and .err files
- Add wget-log and download.log patterns
- Organize under new "Development Logs" section
