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.

Inizia avviando il server di sviluppo e individuando la configurazione che aggiunge la directory .well-known hard-coded o altri documenti statici. Confronta questi input con le sorgenti del filesystem e conferma che la rimozione della configurazione duplicata elimina gli errori del parser e consente di compilare e avviare il sito.
