Vito Sansevero 5485aa8c19 feat(xyz-helpers): add ComfyUI_essentials nodes adaptation
BREAKING CHANGE: Node categories now use emoji-based organization

Add 6 new xyz-helper nodes adapted from comfyui-essentials-nodes:
- FluxSamplerParams: FLUX-optimized parameter generator with batch support
- LoRAFolderBatch: Batch process multiple LoRAs from folders
- PlotParameters: Visualize parameter effects with graphs
- SamplerSelectHelper: Intelligent sampler selection with recommendations
- SchedulerSelectHelper: Optimal scheduler selection for samplers
- TextEncodeSamplerParams: Combined text encoding and parameter management

Changes:
- Port and enhance nodes from comfyui-essentials (now in maintenance mode)
- Add comprehensive documentation with attribution to original author (cubiq)
- Create example workflows for xyz-helpers tools
- Update all node categories to use emoji-based organization
- Fix all unit tests to pass with new category system
- Update README with xyz-helpers section and attribution

Attribution: xyz-helpers adapted from github.com/cubiq/ComfyUI_essentials

All tests passing (318 pass, 2 skip)
