Pylon-dev-rework

[schettn]

This pull request includes several changes to enhance the functionality and maintainability of the @getcronit/pylon and @getcronit/pylon-dev packages. The most notable changes include the addition of a new plugin build hook, the extension of the plugin system, and the replacement of treekill with ps-tree. Additionally, there are updates to the build process to use esbuild watch mode and improvements to the handling of fallback pages and unhandled routes.

Enhancements and New Features:

• Added a new plugin build hook to allow custom esbuild builds, which is called before the main build process. This hook does not re-run during watch mode.
• Extended the plugin system to support middleware and app setup, integrating the viewer via a built-in useViewer plugin. Custom plugins can now access the app instance and register middleware and setup functions.

Build Process Improvements:

• Integrated the builder in the development server to simplify maintenance and future development.
• Updated the build process to use esbuild watch mode instead of rebuilding from scratch.

Dependency and Configuration Updates:

• Replaced treekill with ps-tree in the @getcronit/pylon-dev package.
• Added a fallback page for the landing page and unhandled routes (404s), which can be disabled via the pylon config.
