ComfyUI's v3 validation fan-out repeated one validate_inputs() error string
across every widget input and blocked execute() entirely, so users saw a wall
of duplicate console errors and never saw the actual problem in the node's
own status/help output in the UI.
Removed validate_inputs() from GroqNode and OpenrouterNode; the same checks
(API key required, manual model required, additional_params JSON shape,
audio-model rejection, OpenRouter endpoint policy) now run inside execute()
and return through the node's status output where the UI actually surfaces
them. Updated tests and AGENTS.md to match.
