Links between markdown files are not renamed to .html in the output:

Nobody has claimed this yet.

When markdown links have a `./` in them, html links are not adjusted.
Example:

README.md:
```markdown
Link to [details file](./details.md)
```

details.md:
```markdown
Link back to [README](./README.md)
```

In the generated output the links will be linked with .md extension instead of .html,

in the generated index.html we will get:

```html
Link to details file
```

and in the generated details.html we get:

```html
README
```

which won't work because README.md is converted to index.html

My config.json is as follows:

```json
{
"markdown-to-html": {
"document": {
"title": "Documentation",
"description": "Documentation",
"style": "body { color: red; }"
},
"reurls": {
"details.md": "details.html",
"README.md": "index.html"
}
}
}
```

I call the utility like this:
```
npx markdown-to-html-cli *.md --output "docs-generated" --config config.json
```

Reproduce the issue with the shown README.md, details.md, config.json, and npx command, then inspect the generated index.html and details.html. Trace the CLI's markdown-link rewriting entry point and its handling of ./ paths. Done means links between converted files use the configured .html targets rather than .md extensions.
