State the agent conversation-vocabulary rule in AGENTS.md Every agent that opens this project now reads the rule before it writes its first reply instead of after it has already published something: use the shared private conversation vocabulary in chat, and keep every last word of it out of commit messages, code, docs, issues, releases and this file. The wording is copied verbatim from the canonical instructions and names no term, because the obvious way to explain the rule is to give an example and the example is the leak. Verified with the canonical leak scanner: clean on all 155 needles. 以後開呢個專案嘅代理，未打第一句就已經睇到規矩，唔係漏完先知：傾嘢用內部 講法，但係 commit、程式碼、文件、issue、發佈同呢個檔案，一個字都唔准出現。 條文係逐字照抄，一個詞都唔舉例，因為舉例本身就係漏底。 已經用洩漏掃描器驗過，155 個字全部乾淨。 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
