Fix UI layout: move hidden regen groups outside gr.Row

Fix UI layout: move hidden regen textboxes into invisible gr.Group

Fix UI crash: replace hidden gr.Number with gr.Textbox for regen_seg inputs

Fix fireRegen: use correct prototype for textarea native setter

Disable SSR (ssr_mode=False) to fix regen Too many arguments

Fix regen: single-event trigger + generator-safe early-exit

Fix regen: embed state in trigger value, remove seg_state from inputs

Fix regen: CSS-hidden textboxes + remove _rtrig from outputs to fix Too many args

Fix fireRegen: clear+set pattern for Gradio 5 React .change()

Add regen debug logging + remove console.log noise

.

Fix Too many arguments: separate gr.Group visibility from generation outputs
