Biome v1.7 automates ESLint and Prettier migration

Single-command migration from ESLint and Prettier to Biome, plus experimental JSON reports and staged-file linting.

Summary

Eliminates manual rule porting when consolidating linting and formatting into one tool. The `--staged` flag integrates directly into pre-commit workflows without external dependencies.

Implementation verdict

Replaces dual ESLint+Prettier setup with single Biome config. Requires Node.js for plugin resolution; doesn't support YAML configs yet. Worth migrating now if your ESLint extends supported plugins (TypeScript, React, Unicorn, JSX A11y); test JSON reports first—they're experimental and may change.
