J3vbandClaude Fable 5 3f8e5b59a1 fix(updater): coalesce and negative-cache text-asset fetches (W3-1) ...

FetchTextAssetCached served the unauthenticated, unrate-limited client-update
endpoint. On TTL expiry every concurrent caller missed the cache and issued its
own outbound fetch: a measured 25 requests for 25 callers. Failures were not
cached at all, so an upstream outage produced one outbound request per caller
for as long as it lasted.

Guards the refresh with singleflight so a burst issues one fetch, caches
failures for errorCacheTTL (mirroring the release cache's existing cachedErr
idiom), and evicts expired keys so the map no longer grows by one entry per
release for the process lifetime.
