Implements #406 by adding a --health CLI flag and HEALTHCHECK instruction to the Dockerfile. This allows Docker and container orchestration platforms to monitor container health automatically. Changes: - Added --health flag that validates configuration and plugin connectivity - Implemented HealthCheck() method in pkg/poller/commands.go - Updated Dockerfile with HEALTHCHECK instruction (30s interval, 10s timeout) - Updated MANUAL.md with --health flag documentation - Added health check documentation to Docker README - Added comments to docker-compose examples about built-in health check The health check: - Validates configuration file is found and parseable - Ensures at least one input and one enabled output are configured - Performs basic validation on enabled outputs - Returns exit code 0 (healthy) or 1 (unhealthy) - Runs silently for Docker compatibility 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
