feat: Universal auto-instrumentation for all languages
## New Features
### Universal Instrumentation Container
- Created deploy/instrumentation/ with Dockerfile that downloads OTel agents for:
- .NET (glibc and musl/Alpine versions)
- Node.js (with auto-instrumentation package)
- Python (bootstrap script + requirements)
- Java (javaagent JAR)
- Go (example code for compile-time instrumentation)
- PHP (composer package + init script)
### Universal instrument.sh Script
- Auto-detects application language from running processes
- Generates docker-compose snippets for each language
- Supports: dotnet, nodejs, python, java, go, php
- Usage: ./instrument.sh <container> [language] [otlp_endpoint]
### Improved docker-compose.yml
- Added instrumentation init container with shared volume
- Added AGENT_KEY environment variable for proper auth
- Added ophion-agent service for host metrics collection
- Named containers for easier management
- Added ophion-network for service discovery
### Documentation
- Created docs/QUICK_START.md with:
- Single-command installation
- Instrumentation guide for all languages
- Troubleshooting section
- Authentication guide
### Auth Fixes
- Server now properly validates AGENT_KEY for agent authentication
- OTel Collector configured with AGENT_KEY for forwarding to server
- Fixed 401 errors when agents connect
## Files Changed
- docker-compose.yml: Complete stack with all services
- deploy/instrumentation/*: Universal OTel agent container
- deploy/docker/otel-collector-config.yaml: Fixed auth headers
- instrument.sh: Universal instrumentation script
- docs/QUICK_START.md: Complete quick start guide
- README.md: Updated with new features
- .env.example: Added AGENT_KEY
## Testing
- Go code compiles successfully
- Docker images build correctly
- All changes are backwards compatible
