Default to DeepSeek V4.1 Flash, show API cost in USD, and re-analyze after replacing BOM and netlist.

V4.1 is natively multimodal so every stage uses deepseek-flash; pricing and the UI now surface dollars instead of empty credits. KiCad netlists and neighborhood fingerprints land in the same cut so a second run can keep the project and skip unchanged ICs.
