feat: update DeepSeek models to V4 Flash and V4 Pro (#103)

* feat: update DeepSeek models to V4 Flash and V4 Pro

- Replace deprecated deepseek-chat / deepseek-reasoner with deepseek-v4-flash / deepseek-v4-pro
- Update base URL from api.deepseek.com/v1 to api.deepseek.com
- Update context window (1M) and max output (384K) per official API docs
- Old models deprecated 2026-07-24

* fix: resolveGeneralLLMConfig missing baseUrl + Admiral timeout 180s

resolveGeneralLLMConfig constructed a new LLMConfig but omitted
baseUrl, causing the adapter to fall back to api.openai.com/v1
regardless of provider — DeepSeek keys hit OpenAI (401).
Also raised Admiral preview timeout to 180s for thinking-mode models.

* fix: createTempestCommandInstance missing baseUrl for operator exec

Operator LLM calls also lacked baseUrl, same 401-for-DeepSeek bug
as resolveGeneralLLMConfig. Reads provider-specific baseUrl from config.

* fix(deepseek): migrate retired persisted defaults
