Improving plugin system

[RohitKushvaha01]

• Add support for plugins as javaScript modules and simple single-file plugins, allowing a plugin to be distributed as a single .js file without requiring a ZIP package.
• Implement a permission/scope system using the plugin context api to control plugin capabilities and access.
• Simplify the plugin lifecycle API, which is currently unnecessarily complex and difficult to manage.
• Add a simplified worker abstraction and run new plugins in workers by default, unless explicitly opted out, to reduce performance issues.

Note: This is just an idea
