Fully install and wire Ultracite (Biome-first lint/format) into a JS/TS repo or monorepo: non-interactive init, package scripts, husky + lint-staged, VS Code/editor settings, Prettier/ESLint cleanup, biome.jsonc presets and pragmatic rule overrides, green check, and AGENTS.md notes. Use when the user runs /ultracite-setup, or asks to "add ultracite", "setup ultracite", "init ultracite", "wire biome/ultracite", "replace prettier with ultracite", "lint-staged ultracite", or fully configure monorepo lint/format with Ultracite.
