When scanning a self-hosted Gitea/Forgejo instance, the API may be
reachable at a different hostname than the git clone endpoint (e.g.,
internal API vs. public clone URL behind a reverse proxy). The
--clone-url-base flag rewrites the scheme, host, and port of clone
URLs returned by the API, preserving the path.
Example:
kingfisher scan gitea \
--api-url https://forge.internal.example.com/api/v1/ \
--clone-url-base https://forge.internal.example.com/ \
--user eblume
This avoids routing clone traffic through an external proxy when the
API and git endpoints share the same internal host but the instance's
ROOT_URL points to the public endpoint.
Includes unit tests for the URL rewriting function and an integration
test using wiremock to verify the full enumeration path.
