The generateClaude() function was recursively calling itself inside
enqueueClaude(), creating a circular Promise dependency that permanently
deadlocked the claudeQueue. Any 429 rate-limit response would poison
the queue, blocking all future Claude API calls until server restart.
Fixes:
- Split retries into claudeApiCall() which is called from enqueueClaude
(not re-entering the queue on retry = no circular dependency)
- Max 3 retries with increasing backoff (10s/30s/60s)
- Add resetClaudeQueue() exported function
- Add 15-minute auto-reset stall detection to enqueueClaude
- Expose resetClaudeQueue in POST /api/blog/llm/reset-queue endpoint
- Fix merge conflict markers in index.ts (duplicate scraperRouter import)
