fix: riscv-virt-rt 0.4.1 —— 0.4.0 的零 libc 模板生成出来跑不起来

脚手架会把模板自己的包注入为依赖(好让模板不与库脱节),而本包的模块
#include <stdio.h> ⇒ 在没有 C 库的目标上,那个从未被请求的依赖在工程本身之前就编不过。

0.4.1 声明 [template.inject] self = false(需 mcpp 2026.8.20.2+),并把「没有 C 库」
从错误改为不贡献,同时**照常发模拟器** —— 哪个模拟器能启动这台机器与哪份 libc 无关。

0.4.0 保留:它的默认模板不受影响。

⚠️ 这是本轮唯一一次发布之后才发现的缺陷,发现方式是用发布后的包从零走一遍新用户流程。
