Workaround: manually download and install the skills from https://github.com/basecamp/basecamp-cli/tree/main/skills/basecamp

Reproduce the discovery failure with `yarn dlx skills add basecamp/skills`, then inspect commit `08ef7eaf0f1edc3a22553b95f6512ffd5f51742b` and compare the repository with `basecamp-cli/skills/basecamp`. Done means the repository again contains discoverable `basecamp` and `basecamp-doctor` skills, alongside `hey`.
