chore: sync biome and prettier configs from deepnote/deepnote (GRN-4938)

- Add [email protected] for TypeScript/JavaScript/JSON linting & formatting
- Update prettier to 3.6.2 for Markdown/YAML formatting only
- Remove ESLint dependencies and configuration
- Add new scripts: biome:check, biome:check:fix, lintAndFormat, lintAndFormat:fix
- Update lint-staged to use biome for TS/JS/JSON, prettier for MD/YAML, stylelint for CSS
- Copy biome.json, .prettierrc, .prettierignore from main repo
- Update .gitignore to exclude .biome/ cache
- Apply biome formatting to codebase (single quotes, ES5 trailing commas, semicolons as needed)
- Keep stylelint for CSS (biome doesn't support CSS)
- Maintain jlpm compatibility (no packageManager field)
