New Features:
- TripleKSampler (Advanced Alt) node - static UI variant immune to resize issues
- Stable alternative for users experiencing dynamic UI flickering (see issue #5)
Architecture:
- Refactored class hierarchy: Base → AdvancedAlt → Advanced → Simple (DRY)
- Renamed classes for maintainability (TripleKSampler* from TripleKSamplerWan22*)
- sample() logic now in one place (AdvancedAlt), inherited by other nodes
Documentation:
- Updated README, wiki, and example workflows
- Added stability notes pointing to Advanced Alt node
Backward Compatibility:
- Full compatibility preserved via NODE_CLASS_MAPPINGS keys
- Existing workflows work unchanged
Tests: 125/125 passing
