Setup

Bootstrap a new TypeScript project with the following base tooling:

• Biome (via ultracite presets)
• t3-env for type-safe environment variables
• Knip for unused code detection
• TypeScript with tsgo
• Vitest for testing

Why This Stack

Each tool solves a specific problem in the development workflow:

• Biome (via ultracite) — Single tool for formatting and linting, replacing ESLint + Prettier. Significantly faster due to Rust implementation.
• t3-env — Validates environment variables at startup so missing or malformed values fail immediately instead of causing silent runtime bugs.
• Knip — Detects unused exports, dependencies, and files. Keeps the codebase lean as it evolves.
• tsgo (@typescript/native-preview) — Native Go port of TypeScript's type checker, substantially faster than tsc.
