listTags() follows the registry's Link-header pagination, but the next-page
URL is relative per the OCI/Docker registry spec (e.g.
"/v2/ollama/ollama/tags/list?last=0.9.3-rc5&n=1000"). The code assigned that
raw relative path straight back to `url` and re-fetched it, so fetch() threw
"Failed to parse URL from /v2/...". Any image repo with more than 1000 tags
paginates, so the entire tag list — and therefore the update check — failed
silently for ollama/ollama and filebrowser/filebrowser.
That's the root cause of #945 ("won't update past 0.24.0"): the Ollama
update check never completed, so no newer version was ever offered.
Resolve the next-page URL against the registry origin with
new URL(next, `https://${registry}`), which also passes absolute next-URLs
through unchanged for registries that return those.
Closes#945
