Install or upgrade the Render OpenCode plugin from GitHub.
Requires Node.js 18+ or Bun.

Usage: install.sh [options]

  --config-dir <path>  Target OpenCode config directory; defaults to OpenCode's XDG location.
  --source <path>      Use a local repo checkout instead of downloading from GitHub.
  --enable-mcp        Add Render MCP config, preserving an existing entry unless forced.
  --force             Overwrite user-modified files and existing Render MCP config.
  --dry-run           Preview writes and removals without changing files.
  -h, --help          Show this help.

Unmodified bundled files update automatically. Modified files are preserved.
