Subject: [PATCH] fix: source-aware repo extraction, Gitea readme/languages
 endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use CASE/source instead of COALESCE for repo name extraction — Gitea's
repo.name is the short name while full_name includes the owner prefix.
Fix Gitea README fetch to use /contents/README.md with base64 decoding
instead of the nonexistent /readme endpoint.
