When the Rust hrrr-point-worker marks a task as `failed` (upstream
`idx HTTP 404` or wgrib2 decode error on old archive formats), the
corresponding contacts sit at `hrrr_status = :queued` until the
generic 3-day stale-queued reconcile flips them. Speed that up: on
every BackfillEnqueue tick, join contacts to `hrrr_fetch_tasks` by
rounded HRRR hour and flip any `:queued` contact whose cycle is
permanently `failed` to `:unavailable` immediately.
Motivation: a handful of 2018-08-04/05 cycles (t20z/t21z/t15z/t17z)
are genuinely missing `wrfsfcf`/`wrfprsf` files on the NOAA S3
archive — other hours on the same dates are fine, so this is an
upstream data gap rather than a structural pre-2019 issue. Users
see an accurate "Partial" marker on those contacts instead of a
three-day `:queued` stall.
Tested: 4 new cases covering rounding, failed-vs-done, and the
`hrrr not in types` skip branch; full suite 2283/0.
