test(ai): improve AI package test coverage from 59.7% to 69.5%

Browse source 
Add comprehensive tests for:
- alert_triggered.go: analysis functions (92%+ coverage)
- patrol_history_persistence.go: all store methods (100%)
- patrol.go: helper functions and getters (100%)
- findings.go: Add edge cases, severity escalation (100%)
- Export functions: all config/detector constructors (100%)

New test files created:
- patrol_history_persistence_test.go
- exports_test.go
- service_extended_test.go
- service_remediation_test.go
- service_tools_test.go
- mock_test.go

Also add coverage.html to .gitignore to exclude generated coverage reports.
