The next-minor Packages query used `curl -sf` without -L. pkgs.k8s.io
302-redirects every request to a backing host, so without -L curl returned
an empty body, NEXT_MINOR_PATCH came back empty, and the detector fell
through to "No upgrade needed". That is exactly why last night's 23:00 chain
no-op'd instead of resolving the 1.35 next-minor target (1.35.6) and handing
it to the compat gate. `curl -sfL` follows the redirect and returns the
Packages file (verified: -sf -> empty, -sfL -> 1.35.6). Mirrors the same
-L fix already applied to the Release availability probe (-sILo) above.
