chore: bump Framework 4.2.0 / CLI 3.2.0

[montfort]

Summary

• Bump Framework version from 4.1.1 to 4.2.0
• Bump CLI version from 3.1.1 to 3.2.0
• Update version references across all docs (EN, ES, zh-CN), governance footers, and workflow examples

Crates.io

CI already handles README for crates.io correctly: cp README.md cli/README.md before cargo publish. The updated README with zh-CN language links will be published automatically.

Test plan

• cargo check passes with new version
• No stale version references remain (verified via grep)
• OWASP ASVS control IDs (V4.1.1, V13.1.1, etc.) untouched

Next steps after merge

git tag cli-3.2.0 && git push origin cli-3.2.0
git tag fw-4.2.0 && git push origin fw-4.2.0
