feat: remove lockfile fallback for remote templates (#255)

Removes the behavior of falling back to a base lockfile if the remote template does not contain one.

This is a breaking change for remote templates that were relying on the fallback behavior.

With this change:
- If a remote template has a  file, it's copied over.
- If it does not, no  is created, and the user is expected to generate one.

The documentation has been updated to reflect this new behavior.

 **Best Practice:** Always run `uv lock` after changing dependencies and commit the resulting lock file.
