fix(tests): resolve CI failures - lint, race conditions, and security issues
Fix multiple CI check failures identified in PR #66: - Add missing fmt import to reporting_test.go - Fix unused variables in webhook notification test - Resolve race condition in MockMetricsProvider by adding mutex protection - Fix security issues: reduce file permissions (0750 for dirs, 0600 for files) - Fix linting issues: handle error returns and fix error message capitalization All critical CI checks now pass: - Linting: resolved errcheck and staticcheck issues - Race detection: fixed concurrent access in resilience tests - Security scan: gosec passes with proper file permissions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
