hub v0.101.0 — memoise the artifact dropdown for 60s (R-267, operator ruling)
v0.100.x removed the serialisation: 26.2s -> ~9.85s mean. What remained was one Gitea package SEARCH
per dropdown at 0.20-3.8s depending on load, which concurrency cannot help.

Memoised for 60s IN MEMORY. The TTL was ruled by the operator against the workflow that cares: a
bake-and-vouch session publishes an artifact and comes straight here to select it, so a minute is
short enough not to be noticed and long enough that every reload in that session is instant.

NOT persisted. Gitea IS the store for both the version list and the sha; a copy in hub_settings would
be a second source of truth that can drift from the registry it describes, and the operator reads the
sha here to confirm what they are about to vouch. An in-memory cache dies with the process and can
never be mistaken for a record.

A failed resolve is NOT cached — a blip must not pin an empty dropdown for a minute. But an empty
list from a package that genuinely has no versions IS cached, because 'we found nothing' and 'we
could not look' are different answers (CONTEXT S-39, applied to a list instead of a figure).

THE FIRST VERSION OF THIS GOT THAT WRONG: the comment said only successful resolves were cached and
the code cached the empty list anyway. TestArtifactChoices_FailureIsNotCached caught it before it
shipped — which is the argument for writing the test that asserts the comment, and the same class
this session spent the day closing.

go build/vet/test green, go test -race clean, run separately from this commit.
