The "delete current conversation" feature was not working on Vercel
deployment because the stream flow uses a separate lease mechanism.
The session_id created during prepare phase was not preserved for
deletion when the stream ends.
Changes:
- Add SessionID field to streamLease struct to preserve session_id
- Pass session_id to holdStreamLease during prepare
- Modify releaseStreamLease to return auth and session_id
- Call autoDeleteRemoteSession in handleVercelStreamRelease when
releasing a lease with auto-delete mode enabled
Closes #vercel-auto-delete
- ValidateTurn no longer errors on thinking-only responses, deferring to
ShouldRetryEmptyOutput which now also covers thinking-only outputs.
- Empty output retry uses multi-turn follow-up with a regeneration prompt
suffix and parent_message_id in the same DeepSeek session.
- Centralize StripReferenceMarkersEnabled into textclean package to
eliminate duplicated hardcoded booleans across 4 protocol handlers.
- Log a deprecation warning when the legacy "compat" config key is used.
- Document thinking-only retry and reference marker stripping in API.md.

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
