add search aliases to all nodes (#12035)

* feat: Add search_aliases field to node schema

Adds `search_aliases` field to improve node discoverability. Users can define alternative search terms for nodes (e.g., "text concat" → StringConcatenate).

Changes:
- Add `search_aliases: list[str]` to V3 Schema
- Add `SEARCH_ALIASES` support for V1 nodes
- Include field in `/object_info` response
- Add aliases to high-priority core nodes

V1 usage:
```python
class MyNode:
    SEARCH_ALIASES = ["alt name", "synonym"]
```

V3 usage:
```python
io.Schema(
    node_id="MyNode",
    search_aliases=["alt name", "synonym"],
    ...
)
```

* feat: add SEARCH_ALIASES for core nodes (#12016)

Add search aliases to 22 core nodes in nodes.py to improve node discoverability:
- Checkpoint/model loaders: CheckpointLoader, DiffusersLoader
- Conditioning nodes: ConditioningAverage, ConditioningSetArea, ConditioningSetMask, ConditioningZeroOut
- Style nodes: StyleModelApply
- Image nodes: LoadImageMask, LoadImageOutput, ImageBatch, ImageInvert, ImagePadForOutpaint
- Latent nodes: LoadLatent, SaveLatent, LatentBlend, LatentComposite, LatentCrop, LatentFlip, LatentFromBatch, LatentUpscale, LatentUpscaleBy, RepeatLatentBatch

* feat: add SEARCH_ALIASES for image, mask, and string nodes (#12017)

Add search aliases to nodes in comfy_extras for better discoverability:
- nodes_mask.py: mask manipulation nodes
- nodes_images.py: image processing nodes
- nodes_post_processing.py: post-processing effect nodes
- nodes_string.py: string manipulation nodes
- nodes_compositing.py: compositing nodes
- nodes_morphology.py: morphological operation nodes
- nodes_latent.py: latent space nodes

Uses search_aliases parameter in io.Schema() for v3 nodes.

Add search aliases to audio and video nodes for better discoverability:
- nodes_audio.py: audio loading, saving, and processing nodes
- nodes_video.py: video loading and processing nodes
- nodes_wan.py: WAN model nodes

Uses search_aliases parameter in io.Schema() for v3 nodes.

* feat: add SEARCH_ALIASES for model and misc nodes (#12019)

Add search aliases to model-related and miscellaneous nodes:
- Model nodes: nodes_model_merging.py, nodes_model_advanced.py, nodes_lora_extract.py
- Sampler nodes: nodes_custom_sampler.py, nodes_align_your_steps.py
- Control nodes: nodes_controlnet.py, nodes_attention_multiply.py, nodes_hooks.py
- Training nodes: nodes_train.py, nodes_dataset.py
- Utility nodes: nodes_logic.py, nodes_canny.py, nodes_differential_diffusion.py
- Architecture-specific: nodes_sd3.py, nodes_pixart.py, nodes_lumina2.py, nodes_kandinsky5.py, nodes_hidream.py, nodes_fresca.py, nodes_hunyuan3d.py
- Media nodes: nodes_load_3d.py, nodes_webcam.py, nodes_preview_any.py, nodes_wanmove.py

Uses search_aliases parameter in io.Schema() for v3 nodes, SEARCH_ALIASES class attribute for legacy nodes.
