Add Grafana Alloy configuration files and update examples
- Introduced detailed configuration guidelines in alloy.instructions.md - Added general instructions for project structure in general.instructions.md - Created config.yaml for NAMU-PC with target hostnames - Implemented example.alloy and openwrt.alloy for service discovery and scraping - Added alloy_seed.json for initial configuration state - Developed demo.alloy for comprehensive monitoring setup - Established std.alloy for repository path formatting and host configuration loading - Updated test.alloy to utilize new host configuration loading
