* docs: enforce responsible AI usage
- add the development-assistance rules to AGENTS.md and CONTRIBUTING.md in every locale
- state the AI policy in SECURITY.md
- require AI/LLM disclosure in the issue and pull request templates
- keep the local-reproduction checkbox out of the AI disclosure group
- forbid AI co-author trailers in the commit command
- keep CONTRIBUTING.ko-KR.md and the Korean docs page identical
- import AGENTS.md from CLAUDE.md so Claude Code actually loads the rules
* docs: rewrite AI-usage policy text in original wording
The AI-Assisted Development section (CONTRIBUTING + docs, all locales) and
the SECURITY.md AI Policy were adapted closely from third-party sources
(Kazumi, GPL-3.0; Homebrew, unlicensed). Rewrite the borrowed prose in our
own words with the same meaning, and drop the unrelated Local Reproduction
checkbox from the bug-report template.
