Subject: [PATCH] fix: remove DEEPSEEK_DEBUG gate, always write debug log #8
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- No env var required — logger always active
- console.error fallback on write failure (no more silent catch)
- Tiny output: ~2 lines per session (init + first fetch)
