- Implement automatic environment detection for socket restrictions
- Add LocalPubSub as socket-free alternative to Phoenix.PubSub
- Configure application to adapt PubSub strategy based on environment
- Add comprehensive test coverage for sandbox environments
- Document setup for socket-restricted orchestration runs

Key Features:
- Auto-detects socket availability and falls back appropriately
- LocalPubSub provides compatible API without network dependencies
- Environment variables for explicit configuration
- Graceful degradation when PubSub is unavailable
- Focused mix test commands now succeed in restricted environments

Fixes: NIC-413

This resolves the Mix.PubSub :eperm failures in sandboxed orchestration
by providing socket-free alternatives while maintaining functionality.
