Previously retry/continue requests reused the initial PoW header and
lacked parent_message_id, causing them to land as disconnected root
messages in the DeepSeek session instead of proper follow-up turns.

- Auto-retry Chat/Responses streams once when upstream output is empty but not content-filtered, reusing session/token/PoW and appending a regeneration suffix to the prompt
- Wire DeepSeek continue API into Vercel streams for multi-round thinking output exhaustion
- Defer empty-output errors in stream finalizers to enable synthetic retry; only surface failure when the retry budget is exhausted
- Track content_filter stops to avoid retry on filtered outputs
- Add comprehensive tests for stream/non-stream retry, Responses retry, and content_filter no-retry
- Update prompt-compatibility.md documentation
