Nano Banana MCP (Local Fork)

Fork of nano-banana-mcp with model selection and aspect ratio support.

Changes from upstream

Model selection: Choose between flash (fast/cheap) and pro (slower/better) via env var or per-request parameter
Aspect ratio: Pass aspectRatio to generate_image (1:1, 16:9, 9:16, 3:2, 4:3, 21:9, etc.)
Accurate model labeling: Status output shows actual model name instead of incorrect "Gemini 2.5 Flash"
