Upgrade ESLint to v9 and transition from the legacy `.eslintrc.json` / `.eslintignore` setup to the modern `eslint.config.js` flat config format. The Node.js engine constraint is set to `>=18.18.0` to match the default Node.js version provided by Ubuntu 24.04 LTS (Node 18.19.1) and the minimum requirement for the last ESLint 9.x version (10.x requires Node 20). Note: the actual configuration applied has not changed in this commit. Summary of changes: - Upgrade `eslint` to 9.x and add `@eslint/js` and `globals` dependencies. - Add Node 18.18+ requirements - Consolidate ignore patterns, globals, and rules into `eslint.config.js`. - Remove an obsolete inline ESLint directive in `polyfill_command_api.js`.
Adopt the Web Platform Baseline ("widely available") target as our
standard browser compatibility policy for runbot JS code.
The "Baseline Widely available" standard represents features supported
across all major browser engines (Chrome, Edge, Firefox, Safari) for at
least 30 months, ensuring safe, polyfill-free compatibility.
Summary of changes:
- Define `"browserslist": ["baseline widely available"]` in
`package.json` for reference and tooling.
- Integrate `eslint-plugin-compat` in ESLint's config to
automatically catch unsupported JS features during linting.
