Scaffolds the toolkit with a scalable layout (src/deepsoch_toolkit
package, per-category node subfolders, shared core helpers, shipped vs
user-writable preset directories) and ships four nodes:
* Prompt Preset (deepsoch/prompt) — checkbox-based multi-select over a
preset library, with select_all toggle and optional custom prompt;
outputs as a STRING list so downstream auto-runs once per prompt.
* Load Images (deepsoch/image) — upload-multi widget with native-style
multi-image preview (grid + click-to-fullscreen, X close, counter
cycling) mirroring ComfyUI's SaveImage UX via onDrawBackground.
* Set Node / Get Node (deepsoch/util) — wireless reroutes implemented
as Python stubs enhanced by JS into virtual nodes; getInputLink /
getInputNode redirect graph traversal through the matching Set.
