feat: propagate workflow output language

[ddddddddwp]

Summary

• Add an output-language rule to the main Comet workflow so generated artifacts follow the triggering user request language.
• Pass that language constraint into OpenSpec and Superpowers steps across full, hotfix, and tweak workflows.
• Add safeguard coverage and a changelog entry for issue feat: make superpowers and openspec outputs follow the user's language #37.

Test Plan

• npx vitest run test/ts/skills.test.ts
• git diff --check origin/master..HEAD

Notes

• Full npx vitest run currently fails in test/ts/init-e2e.test.ts because the clean-directory init fixture cannot find .claude/skills in the temporary Lingma Superpowers staging directory, which also leaves .codex/skills/comet/SKILL.md absent.

Code Review

This pull request introduces output language constraints across various Comet workflows and skills (both English and Chinese versions) to ensure that generated artifacts, proposals, plans, and reports respect the language of the triggering user request. It also adds corresponding test coverage to safeguard these language rules. A review comment suggests optimizing the test file by reading the skill markdown files concurrently using Promise.all instead of sequentially.

Reading 16 files sequentially using await fs.readFile blocks the event loop and can slow down test execution, especially in CI environments with slower disk I/O. We can optimize this by reading all files concurrently using Promise.all.
