HoneyandClaude Sonnet 4.6 eb5b0ea360 fix: lrclib rate limit — exact first, then 2 parallel searches; check HTTP 200
3 simultaneous requests were hitting lrclib rate limiter.
Now: exact match alone → if no content, 2 parallel searches.
Also check response.status === 200 before parsing to avoid treating
404/429 error bodies as valid empty lyrics responses.
