fix(process-continuity): operator-free design for MCP Docker integration

- Resolve service_healthy deadlock by using service_started instead
- Fix 172.28.0.0/16 network collision by removing ipam config
- Add HybridGiteaClient (mcp → rest → bash fallback)
- Create .kilo/rules/process-continuity.md with 5 operator-free principles:
  1. No service_healthy conditions
  2. No hardcoded networks
  3. Automatic fallback chains
  4. Pre-flight validation
  5. Self-documenting failures
- Update docker-compose.yml with resilient config:
  - start_period: 60s, retries: 5, restart: on-failure:3
  - /tools healthcheck (guaranteed endpoint)
  - tmpfs for Node.js /tmp
  - Resource limits: 256M RAM, 0.5 CPU
- MCP/REST integration test passed (issue #109)
