"""开发联调 JWT 签发 CLI（T-01 · 仅 development；生产由 IdP 签 RS256）。

用法（Git Bash / PowerShell）：
    python scripts/dev/issue_dev_token.py --sub STAFF-30001 --roles risk_officer
    python scripts/dev/issue_dev_token.py --sub CUST-9527 --roles customer \\
        --token-type customer --customer-id CUST-9527

签发后经 `Authorization: Bearer <token>` 调用，JWT 通道须带 `X-Agent-Type`
（手册 §4.6）。HS256 密钥取 .env JWT_DEV_SECRET；APP_ENV != development 时
拒绝签发（防止对称密钥流出）。
