v0.8.0

Performance Improvements

• SqliteCache migration — eliminated O(N²) bottleneck from DiskCache
• Rate limiter jitter — prevents burst-stall pattern with ±10% timing variance
• HTTP connection pooling — 50 max connections, 20 keepalive (5x increase)
• Shared HTTP client reuse — eliminates redundant DOI validation connections

Bug Fixes

• Per-service rate limiting — RateLimiterRegistry now consistent across all modules
• Correct service names — fixed mismatched identifiers in rate limiter config
• Missing service parameter — crossref search now properly rate limited
