issue: Duplicate path error during build

While running the project locally (served on 127.0.0.1:8000), the typelevel.github.com fails during parsing with multiple duplicate path errors.

Below is the attached screenshot of error message:

This causes the site build to fail and prevents the server from starting successfully.

Possible Cause:
This may be happening due to:

1. Multiple input directories being merged (e.g., duplicate InputTreeBuilder sources).
2. The same .well-known directory being included twice in configuration.
3. A custom Laika configuration adding static documents that conflict with filesystem inputs.
   Based upon my observations:
   This issue is caused due to hardcoding the ".well-known" -

Steps to Reproduce:

1. Clone the repository
2. Run the development server
3. Observe parser failure with duplicate path errors

Suggested fix:
I would suggest removal of the hard-coded .well-known Directory, post of removal the build works absolutely fine.

Would like to raise a PR to fix this issue.

まず開発サーバーを起動し、ハードコードされた .well-known ディレクトリやその他の静的ドキュメントを追加している設定を特定します。それらの入力をファイルシステムのソースと比較し、重複した設定を削除することでパーサーエラーが解消され、サイトをビルドして起動できることを確認します。
