Publishing v1.7.121-alpha failed on auth after the manifest had already
passed every check. The script required an `http://user:token@` remote,
which left only `gitea-vps2` — whose token is dead — and rejected
`gitea-ai`, the https remote whose credential actually works for git
push. Same Gitea instance (146.59.87.168, v1.27.1) either way, so the
restriction bought nothing and blocked the one usable path.
Accepts http and https, and carries the scheme through to the API URL
instead of hardcoding it.
Note for diagnosis next time: `/api/v1/repos/.../releases` is publicly
readable, so a 200 there does NOT prove the credential works. Use
`/api/v1/user`, which requires real auth.
