Replace @shopify/eslint-plugin + eslint + eslint-plugin-jest with Oxlint (https://oxc.rs/docs/guide/usage/linter), a Rust-based linter ~50–100x faster. Changes: - Delete eslint.config.js, add oxlint.json with equivalent rule config - Update all 20 package lint scripts from `eslint .` to `oxlint .` - Remove ESLint devDependencies (eslint, @shopify/eslint-plugin, eslint-plugin-jest) and add oxlint@^1.0.0 - Run Prettier as a standalone `prettier` script instead of via ESLint; fix .prettierignore glob patterns for remix/react-router example files - Fix 42 Oxlint violations introduced by stricter rule enforcement: - no-non-null-asserted-optional-chain in billing helpers and express config - no-unsafe-optional-chaining in request-mock.ts (remix + react-router) - no-unused-vars: rename catch params to _error/_err, remove unused imports Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Why
ESLint (with
@shopify/eslint-plugin) has accumulated significant startup overhead and transitive dependencies. Oxlint is a Rust-based linter that is ~50–100x faster, with a much smaller dependency footprint.What

All CI checks pass (lint + tests across Node 20/22/24).
