* Extract plugin

* Remove vitepress-plugin-mermaid

* Prepare for mermaid integration

* pre-render graphs

* Remove unnecessary dependencies

* Of course we also need to render during build

* Update

* Create graphs directory if missing

* Rename deoptimizeThis to refer to arguments and make thisArg optional

* Extract ParameterVariable from ThisVariable

* Use ParameterVariables for parameters

* Move argument deoptimization into deoptimizeArguments

* First attempt at selective parameter deoptimization

While this seems to work, it has abysmal performance as evidenced by the
core-js test. A better approach might be only deoptimize top-level parts.

* New approach with better performance

* Improve handling of functions returned by functions

* Clear some TODOs

* Sometimes, we need to do nothing

* Do not deoptimize arguments to global calls by default

* Fix linting

* Improve coverage

* Improve coverage and simplify code

* Update dependencies
