test: add unit tests for hook quoting fix (Issue #73)
Add comprehensive test suite for convertToClaudeCodeFormat function: - Verify bash -c commands use single quotes - Verify jq patterns are preserved without excessive escaping - Verify single quotes in scripts are properly escaped - Test all real-world hook templates (danger-*, ccw-notify, log-tool) - Test edge cases (non-bash commands, already formatted data) All 13 tests passing.
