Subject: [PATCH 2/4] Add editorconfig aligned with shared formatting baseline.

This commit defines line ending/newline defaults and per-file indentation rules so local editors match the shared Prettier policy across JS/TS, JSON, YAML, Markdown, and Makefiles.

Subject: [PATCH 3/4] Document how to consume the shared formatting baseline.

This commit upldate the documentation to explain the new Prettier baseline,
recommended adoption steps, and editor alignment so downstream repositories
can import and apply the config consistently.

 * Provides an `eslint-config-scality` package that can be added as a dependency
   in other projects. That way, coding style can automatically be checked using
   eslint.
+
+## Prettier baseline
+
+This repository also provides a **baseline Prettier configuration** for Scality
+object repositories: 4-space JavaScript/TypeScript indentation, 120-character
+line length, single quotes, semicolons, trailing commas, and
+`quoteProps: 'as-needed'`.
+
+The configuration lives in `prettier.config.cjs`.
+
+To use it in a project:
+
+1. Install Prettier in the project:
+
+   ```sh
+   yarn add --dev prettier
+   # or
+   npm install --save-dev prettier
+   ```
+
+2. Copy or extend the configuration:
+
+   ```js
+   // prettier.config.cjs
+   module.exports = require('eslint-config-scality/prettier.config.cjs');
+   ```
+
+3. Add convenience scripts:
+
+   ```json
+   {
+     "scripts": {
+       "format": "prettier --write .",
+       "format:check": "prettier --check ."
+     }
+   }
+   ```
+
+Projects may override options locally (for example `tabWidth` or
+`printWidth`) if they have strong legacy constraints, but this configuration
+is intended to be the **default Scality baseline** for new or reformatted
+Node.js codebases. YAML/JSON/Markdown files default to a 2-space indentation
+and Markdown prose is left un-reflowed by default (`proseWrap: 'preserve'`),
+to avoid noisy diffs in existing documentation.
