avante repo map cli as a standalone tool

[GopherJ]

It'll be good to publish avante repo map as a standalone tool as people need to extract code summary and feed to gpt so that they can ask questions

[GopherJ]

basically a tool traversing each file in the directory and extract the code summary + file path

[GopherJ]

I'm currently using a hacking version:

function code-summary
    if test -n "$argv[1]"
        tree $argv[1]
        find $argv[1] \
          -name "*.$argv[2]" \
        | xargs -I {} avante-repo-map-cli $argv[2] {}
    end
end

// code-summary ~/Projects/my-project rust

but my avante-repo-map-cli is really outdated comparing to the master
