feat: Convert config.js to config.yaml (Issue #55)

[EmersonFras]

Summary

Replaces public/config.js with public/config.yaml as the sole configuration entry point for the catalog template. Configuration is fetched asynchronously at runtime via fetch('config.yaml') and parsed with js-yaml.

Changes Made

• public/config.yaml - New YAML config file replacing config.js. Contains all the same settings (org name, branding, colors, API URL, additional repos, font) with inline comments.
• public/config.js - Deleted.
• main.js - Removed the synchronous CONFIG global check and top-level const destructuring. Added import jsYaml from 'js-yaml' and a module-scope configPromise that starts fetching config.yaml immediately when the module loads (before DOMContentLoaded), so the network request is in-flight while the DOM parses. Inside DOMContentLoaded, config is awaited before anything else runs; CSS custom properties, document title, font link, and favicon are all applied from the resolved config. A visible error banner and safe defaults are used as fallback if the fetch fails.
• style.css - Added --color-accent-dark and --font-family to the :root block alongside the existing color defaults. These two properties had no :root fallback before, meaning they would render as unset during the async config fetch. The hardcoded values match the YAML defaults and are overridden by JS once config loads.
• index.html - Removed <script src="config.js"> and three inline <script> blocks that synchronously applied config (CSS vars, font update, favicon). Kept the dark mode toggle script (it does not depend on CONFIG) and the static <link id="font-link"> tag with the Inter default.
• scripts/export-tags.js - Replaced the regex + new Function() approach for extracting CONFIG from config.js with a direct jsYaml.load(fs.readFileSync('public/config.yaml')) call.

Pull request overview

This PR migrates the catalog’s configuration from a JavaScript global (public/config.js) to a YAML file (public/config.yaml) that’s fetched at runtime and parsed with js-yaml, aiming to keep configuration comment-friendly while avoiding executing arbitrary JS.

Changes:

• Add public/config.yaml and remove public/config.js as the configuration source.
• Update main.js and index.html to asynchronously fetch/parse config and apply branding/CSS/font/favicon at runtime.
• Update scripts/export-tags.js to read YAML directly, and add js-yaml as a dependency.

Looks good, though the README should also be updated to reflect the change.
