c335a1f: Add **/node_modules and **/.git to the shared ignore patterns. oxlint only skips node_modules when a .gitignore lists it, so in projects without one, ultracite fix would lint and autofix files inside node_modules — corrupting installed packages (e.g. rewriting var enum wrappers in typescript/lib/typescript.js to self-referencing const, causing “Cannot access ‘Comparison’ before initialization” when oxlint loads eslint-plugin-sonarjs). Fixes #737.
