build: Cleanup build scripts and watchers

[rkaraivanov]

Description

• Dropped node-watch dependency and replaced it with native fs.watch
• Updated build-styles.mjs to use a single buildAll function instead of separate buildThemes and buildComponents functions
• Improved logging in stories-watcher.js to include timestamps and better error handling
• Updated dev dependencies in package.json

[Copilot]

Pull request overview

This PR streamlines the local/build tooling by removing the node-watch dependency in favor of Node’s native fs.watch, consolidating Sass build steps behind a single buildAll() entrypoint, and refining story metadata generation/logging.

Changes:

• Replace node-watch usage with native fs.watch in the SCSS and stories watchers.
• Add buildAll() to unify theme + component Sass generation and update build scripts to use it.
• Refactor build-stories.mjs for more robust manifest parsing/type handling and reduce unnecessary file writes; bump several dev dependencies.
