Strength bars behind each row's name (name doubles as a scrub surface),
the absorb-chain gear action (core/rgthree/Pixaroma/AusBoss loaders,
both directions, originals bypassed), moved-file resolution at run time
with warn-and-skip for missing files plus the reconnect button riding
ComfyUI's R refresh, folder-free row names, the amber duplicate ring,
master-toggle memory, the control bar reclaiming the slot band, + LoRA
inside the stack, and unified strengths as a hard per-node default.
Pure logic merged from the lab's lora_lab.mjs into lora_stack.mjs;
settings_menu gains action rows and persist:false; _lora_helpers gains
match_lora_name and the resolve fallback; VALIDATE_INPUTS is structural
only so a missing file can never block the queue.
