Better support for support for combined "markdown + clojure" files

[behrica]

I am dealing lately more and more with markdown files which have Clojure code blocks in it.
(LLMs produce them in reasonable quality of text and code)

The "review" of the codeblocks is currently not very comfortable with Calva , as the files are not .clj files.

So most Calva features do not work (except 'Evaluate Current form or Selection.')

It might be a good start to be able to:

• execute such a single code block in one command
• execute all code blocks

see here as well:

I think we need to "think" about this a lot.
If we wanted to be serious on this, we needed allowing "2 languages modes per file".
(which vscode is not supporting)

"Larger codeblocks" become very quickly very uncomfortable to work with.
even when having some "keyboard shortcuts" to send a block to the repl (which I got woking with some tricks and "multi-command" extension)

We are then in "sending as-is ok, editing bad" situation.

It does "somehow work" to change the language mode manualy to "clj", but then Calva gets very slow,
maybe because the "markdown" file is in fact invalid clojure syntax....

I think it works better the other way arround.
So have a normal clojure file, where comments can be markdown.

then we would only have a way to render this "markdown" in a side panel.

There is the "markdown-everywhere" plugin but it has some "bugs" for Clojure...
Maybe this could become a Calva feature and optimized to work for Clojure and its "comment" syntax ?

This "markdown in ;;" syntax is supported by "Clay" and "Clerk"

I have no idea on VsCode extensions, but I was reading that a TextDocumentContentProvider could be created which somehow shows the clj file as "markdown", assuming that all lines with line comments ";;" jave text in markdown syntax
