Demonstration of Search Provider Timeout Fixes

This script shows how the timeout issues identified by the debugger subagent have been resolved:

BEFORE (Issues):
- Complex queries failed at exactly 10 seconds
- Circuit breakers were too aggressive (5 failures = disabled)
- No distinction between timeout and other failure types
- Budget allocation wasn't optimal

AFTER (Fixed):
- Complex queries get up to 25 seconds
- Circuit breakers are more tolerant (8 failures, faster recovery)
- Timeout failures have separate, higher threshold (12 vs 6)
- Better budget allocation with minimum timeout protection
