fix: add LICENSE, fix check-destructive.sh bugs, align read routing table

- Add MIT LICENSE file (2026 Tw93); README badge was linking to a 404
- Fix grep -F pattern bug: 'git checkout \.' never matched 'git checkout .'
- Fix --no-verify being parsed as a grep flag; use grep -qF -- to end options
- Add -m1 to version grep in CLAUDE.md to avoid matching body text
- Add mp.weixin.qq.com row to read/SKILL.md routing table to match README
