Release v0.2.1

NerazimNet v0.2.1

Highlights

• ARM64 VPS support. Provisioning now detects the remote CPU architecture via uname -m and downloads the matching frps archive, so ARM VPS tiers work out of the box — Hetzner CAX, Oracle Cloud Ampere, AWS Graviton. amd64, arm64, arm (v6/v7), and 386 are mapped; anything else fails with a clear message instead of installing a broken binary.
• Port ranges in Extra Service Ports. Layer-4 schemes accept ranges — udp:50000-50020:localhost:50000-50020 — rendered as a single FRP range: proxy, one Nginx stream listen range (proxied via $server_port), and a ufw lo:hi rule. Built for LiveKit/WebRTC-style services that need contiguous UDP blocks. Ranges require a raw:/tcp:/udp: scheme and equal-length remote/local ranges.
• Desktop notifications on tunnel drops. When a running tunnel errors, you get an OS notification; another fires when it reconnects. Transitions only — no repeat spam while a tunnel stays down, and no alerts for deliberate stops. Tray balloon on Windows, Notification Center via osascript on macOS, notify-send on Linux.

Development

• 11 new tests (36 total): arch mapping, extra_ports range parsing and frpc config rendering, Nginx stream template output, and notification transition behavior.
