feat: 重组为标准 skill 包结构 + 修复 verify.sh bash 3.2 兼容

- 新增 .claude/skills/new-project/SKILL.md（标准 skill 格式）
- install-skill.sh 安装时组装 SKILL.md + verify.sh，单一源无重复
- verify.sh 改用索引数组替代 declare -A，兼容 macOS bash 3.2
- log_pass/log_skip 显式 return 0，避免 set -e 下非 verbose 误退出
- README 改为 skill 优先；补全 copier.yml/scripts/template 入库
