Add option to only exclude in "Repository Files", but not in "Repository Structure"

Hi @yamadashy , really nice work. I love this tool.

By the way, why don't you add option only exclude in "Repository Files"?
Currently, --ignore option both exclude in "Repository Structure" and "Repository Files".

For example, my target repository has this kind of file:

📈 Top 5 Files by Character Count and Token Count:
──────────────────────────────────────────────────────
1.  apps/frontend/src/app/fixtures/transcripts1.json (1145024 chars, 377136 tokens)
2.  apps/frontend/public/locales/en/common.json (192476 chars, 82151 tokens)
3.  apps/admin/public/assets/CompanySign.svg (185918 chars, 132207 tokens)
...

In this case, I don't want to store file content but want to include in repository structure.

I think --exclude option is one good name for this purpose.

Thanks for the great suggestion! I agree that keeping files in the structure while excluding their content would be really useful.

I considered using --exclude, but it might cause confusion with the existing --ignore option.

Instead, here's my initial draft:

{
  "ignore": {
    "useGitignore": true,
    "useDefaultPatterns": true,
    "customPatterns": ["node_modules/**"],
    "ignoreContentCustomPatterns": ["**/*.svg", "**/*.json"]  // New option
  }
}

CLI would be:

--ignore-content "**/*.svg,**/*.json"

This preserves existing behavior while adding content-only exclusion. Still thinking through the naming though - what do you think about this approach?
