Add Docker Compose Amnezia WireGuard + 3proxy/V2Ray configs and client examples

[krotname]

Motivation

• Provide a self-contained Docker Compose stack to run a WireGuard client connected to an Amnezia server and expose authenticated 3proxy SOCKS5/HTTP and an optional V2Ray service for tunneling.

Description

• Update README.md with usage instructions, notes about replacing placeholder values, and examples for starting the stack with docker compose up -d and the v2ray profile.
• Add docker-compose.yml defining wireguard, proxy (3proxy) and optional v2ray-server services with logging.driver: "none" and network_mode: "service:wireguard" for the proxy.
• Add server/config templates wireguard/wg_confs/wg0.conf, proxy/3proxy.cfg, and v2ray/server-config.json containing placeholder values to be replaced before use.
• Add client examples client/proxy.env.example, client/proxychains.conf, and client/v2ray-client.example.json showing how to configure HTTP_PROXY/ALL_PROXY, proxychains, and a V2Ray client respectively.

Testing

• No automated tests were modified or executed as part of this change.
• Existing project test suite (Java kata tests) was not affected by these infrastructure and documentation additions.
