Remove useless group argument from desc.Node attributes

[Copilot]

group on attributes is only meaningful for desc.CommandLineNode (used to construct CLI argument groups). All nodes in this repo extend desc.Node, making every group= declaration a no-op.

Changes

• All node files — remove group="" from input/output attribute definitions across all 9 nodes (ImageBiRefNetMatting, ImageDetectionPrompt, ImageSegmentationBox, ImageSegmentationPrompt, ImageSegmentationSam3, ImageTagsExtraction, SDMatte, VideoSegmentationSam3, VideoSegmentationSam3Text)

• FilterMasks.py — remove group="opt" from the 5 optional filter parameters (kernel_size, kernel_shape, iterations, use_of, smoothing_strength) and replace the runtime introspection that relied on it with an explicit parameter name list:

# Before — abused group= as a runtime tag
for a in chunk.node.attributes:
    if a.desc.group == 'opt':
        kargs[a.name] = a.value

# After — explicit list
optParams = ['kernel_size', 'kernel_shape', 'iterations', 'use_of', 'smoothing_strength']
for a in chunk.node.attributes:
    if a.name in optParams:
        kargs[a.name] = a.value
