Adds idempotency guard to prevent race conditions when multiple users
submit commands for the same play simultaneously.
Changes:
- Add PlayLockedException for locked play detection
- Implement lock check in checks_log_interaction()
- Acquire lock (play.locked = True) before processing commands
- Release lock (play.locked = False) after play completion
- Add warning logs for rejected duplicate submissions
- Add /diagnostics endpoint to health server for debugging
This prevents database corruption and duplicate processing when users
spam commands like "log xcheck" while the first is still processing.
Tested successfully in Discord - duplicate commands now properly return
PlayLockedException with instructions to wait.

Implements a comprehensive health check system using aiohttp to support
container orchestration and external monitoring systems.
Features:
- /health endpoint: Basic liveness check (is process running?)
- /ready endpoint: Readiness check (is bot connected to Discord?)
- /metrics endpoint: Detailed bot metrics (guilds, users, cogs, latency)
Changes:
- Add aiohttp to requirements.txt
- Create health_server.py module with HTTP server
- Update paperdynasty.py to run health server alongside bot
- Update docker-compose.yml with HTTP-based healthcheck
- Fix deploy.sh Docker image name
Benefits:
- Auto-restart on bot hangs/deadlocks
- Foundation for external monitoring (Prometheus, Grafana, etc.)
- Detailed diagnostics for troubleshooting
- Industry-standard health check pattern
