Greptile Summary

Fixed block naming behavior when pasting blocks into workflows. Previously, blocks always received a " 1" suffix (e.g., "Pages" → "Pages 1") even when no naming conflicts existed. Now preserves original names when no conflicts are detected, only applying getUniqueBlockName when actual collisions occur.

Changes:

• Added conflict detection check using normalizeName for case-insensitive comparison
• Preserves original block names when no conflicts exist in destination workflow
• Maintains correct collision handling when conflicts do occur
• Added 9 test cases covering happy path, edge cases, and collision scenarios

The fix correctly handles:

• Blocks without conflicts (preserves original name)
• Exact name matches (increments number)
• Case-insensitive conflicts (e.g., "api 1" vs "API 1")
• Multiple blocks with same name in paste set (prevents self-collision)

Confidence Score: 5/5

• Safe to merge with no risk
• Simple, focused bug fix with comprehensive test coverage (9 new tests). Logic is straightforward and correctly preserves names when no conflicts exist while maintaining proper collision handling
• No files require special attention
