Add intuitive semantic parameters for working with IF and Switch nodes:
- branch='true'|'false' for IF nodes (maps to sourceOutput)
- case=N for Switch nodes (maps to sourceIndex)
- Smart parameters resolve to technical parameters automatically
- Explicit parameters always override smart parameters
Implementation:
- Added branch and case parameters to AddConnectionOperation and RewireConnectionOperation interfaces
- Created resolveSmartParameters() helper method to map semantic to technical parameters
- Updated applyAddConnection() to use smart parameter resolution
- Updated applyRewireConnection() to use smart parameter resolution
- Updated validateRewireConnection() to validate with resolved smart parameters
Tests:
- Added 8 comprehensive tests for smart parameters feature
- All 141 workflow diff engine tests passing
- Coverage: 91.7% overall
