Fix IN Clause Formatting

[xterao]

Summary

This PR fixes an issue where test data used inside an IN clause was unintentionally broken into multiple lines during SQL formatting.

Relation

#397

Details

• Implemented a dedicated IN clause group block so that IN clauses are explicitly recognized and formatted correctly.
• Added a function to determine whether a conditional directive is positioned before its parent block.
• Updated the parent-child relationship logic for conditional directives so that their positions are correctly identified. This ensures proper control over when line breaks should or should not be applied.

Impact

• Prevents unwanted line breaks in IN clause test data.
• Ensures consistent formatting of SQL containing conditional directives, avoiding misaligned or unnecessary newlines.
