feat: add structured logging to serp_api.py

Add module-level logger to serp_api.py with INFO-level messages for patent queries and PDF downloads, and DEBUG-level messages for cache hits and parsing details. All three target files (analyzer.py, serp_api.py, llm.py) now use structured logging with no print() calls. Closes leeworks-agents/SPARC#46 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
