One-time founder onboarding — generates personalized manifest, STREAM calibration, dev principles, and stack selection. Use when user says "set up solo factory", "initialize profile", "configure defaults", "first time setup", or "onboard me". Safe to re-run. Do NOT use for project scaffolding (use /scaffold).

一次性创始人接入——生成个性化清单、STREAM 校准、开发原则和栈选择。当用户说“设置单人工厂”、“初始化配置”、“配置默认值”、“首次设置”或“帮我接入”时使用。可安全重复运行。请勿用于项目脚手架（请使用 /scaffold）。
