average_weights (formerly normalize) ON computes a weighted AVERAGE
(÷Σweights), which silently halves stacked LoRAs -- the original "normalize
kills my LoRA" complaint. Native ComfyUI stacks LoRAs additively
(W + Σ strengthᵢ·Δᵢ), so OFF (additive sum) is the least-surprising default.
Flipped the widget + signature defaults True->False on Task Arithmetic,
TIES, DARE, DELLA (Breadcrumbs was already False). Also fixes the latent
`average_weights: bool = 0.5` default on Task Arithmetic. Tooltip updated to
say OFF matches ComfyUI stacking; turn ON only to blend/interpolate.
Safe for saved workflows: widget values serialize positionally, so existing
nodes keep their stored value; only newly-added nodes get the new default.
New guard test asserts the default is False on all GTA method nodes.
