Add a name and separator before contents?

[bogorad]

With these new LLMs with a million-token content window it doesn't make sense to use RAG any longer, it's better just copy your whole codebase. I use a separate utility for this, but if this plugin allowed prepending the file name to the contents, it'd be so much easier!

E.g.,

README.md:
'''
contents
...
contents
'''

server/server.js:
'''
contents
...
contents
'''

etc. Delimiters and file name format configurable :)
