Zoltán Papp e3a5c44d37 Add client metrics system with OpenTelemetry and VictoriaMetrics support ...

Implements a comprehensive client metrics system to track peer connection
stages and performance. The system supports multiple backend implementations
(OpenTelemetry, VictoriaMetrics, and no-op) and tracks detailed connection
stage durations from creation through WireGuard handshake.

Key changes:
- Add metrics package with pluggable backend implementations
- Implement OpenTelemetry metrics backend
- Implement VictoriaMetrics metrics backend
- Add no-op metrics implementation for disabled state
- Track connection stages: creation, semaphore, signaling, connection ready, and WireGuard handshake
- Move WireGuard watcher functionality to conn.go
- Refactor engine to integrate metrics tracking
- Add metrics export endpoint in debug server
