User asked to "copy the Load PLY node from HallettVisual/comfyui-
GaussianViewer". After cloning + reading the source, that repo doesn't
ship a LoadPLY node — every PLY input there is forceInput-only
(GaussianViewer / GeomPackRenderGaussian / ExtrinsicsToPose). So
writing one from scratch in the spirit of the request.
`load_ply.py` scans both ComfyUI's input/ AND output/ directories
recursively for .ply files; the combo entries are prefixed with the
folder kind ("input/foo.ply", "output/lito_output.ply") to disambiguate
collisions. LiTo's LiToExportPLY writes to output/, so its files appear
in the dropdown directly — no manual copying.
Implements:
- INPUT_TYPES re-scans on each schema evaluation (no stale lists).
- IS_CHANGED keys on the picked file's mtime so re-runs catch edits.
- VALIDATE_INPUTS rejects entries that disappeared between schema
fetch and execute.
Output is a STRING `ply_path` (absolute), so it slots directly into
PreviewGaussians / GaussianMerge's `ply_path` forceInput. Lets users
preview an arbitrary PLY without re-running LiTo, or pipe a
hand-edited PLY into GaussianMerge.

ComfyUI-GaussianPack
Tiny Gaussian-splat turntable viewer for ComfyUI. One node, Preview Gaussians, with a
gsplat.js WebGL preview and camera-intrinsics widgets (FOV, image width, image height).
