Arche Code v1.0.1

• New arche setup command for re-running model selection anytime
• Interactive model picker with numbered list, multi-select, and all option
• Model catalog expanded to 6 variants across three families (500M, 3B, 12B MoE) — adding future models requires one line of code

• Agent step history capped at 3 entries to prevent prompt bloat in long loops
