Subject: [PATCH] Add optional proxy support via MC_PROXY environment variable

Allows users behind network restrictions (e.g., mainland China) to route
download traffic through a local HTTP/SOCKS5 proxy by setting the
MC_PROXY environment variable.

Usage: $env:MC_PROXY='http://127.0.0.1:7890'; .\start.ps1

- When MC_PROXY is not set: behavior is completely unchanged
- When MC_PROXY is set: all Invoke-WebRequest calls and the Java
  packwiz process use the specified proxy
