/**
* RenameNodeTool Unit Tests
* ISO/IEC 29119 compliant - covers uncovered lines:
* 49, 54, 59, 99, 117-118, 124-139, 155-156
*
* These tests exercise:
* - Project validation error return (line 49)
* - Scene validation error return (line 54)
* - Empty new name validation (line 59)
* - Sibling name collision (line 99)
* - Nested parent path updates (lines 117-118)
* - Connection from/to name updates (lines 124-139)
* - Error handling catch block (lines 155-156)
