Wrapper 命令对 env 值进行双重转义: Ec() 为未引号的设置进行转义,但 ce() 会输出带引号的设置"KEY=…",因此括号/%% 会存活到子环境中(带 () 的模型名称会以 ^(self hosted^) 的形式出现)

Wrapper cmd double-escapes env values: Ec() escapes for unquoted set, but ce() wraps in quotes, so quoted set "KEY=..." never unescapes → model names with () arrive as ^(self hosted^)
