ginuerzh 55a246869e fix(metrics): add cross-platform process metrics collector for non-Linux systems 
The standard Prometheus ProcessCollector uses procfs (Linux-only /proc),
so process_resident_memory_bytes and process_virtual_memory_bytes were
silently absent on FreeBSD, Darwin, and other non-Linux platforms.

- Switch to a custom prometheus.Registry to isolate GOST metrics from
  the default registry auto-registrations
- Add gopsutil/v3-based process collector (process_other.go) for
  platforms without procfs (!linux && !windows)
- Keep standard ProcessCollector (process_standard.go) on Linux/Windows
- Update metrics service and handler/metrics to serve from
  promhttp.HandlerFor(customRegistry) instead of promhttp.Handler()
- Add Registry() accessor for the custom registry

Fixes go-gost/gost#509

ginuerzh 785d52da31 feat(metrics): add CORS headers for browser-based metrics access 
Allow browser-based dashboards (e.g. Flutter web apps) to access the
metrics endpoint by setting Access-Control-Allow-Origin: * and handling
OPTIONS preflight requests.
