A gbrain-unreachable failure in fetchRecentDecisions and fetchSalience
used to be converted into a cached 'successful' empty digest ("_No prior
skill runs recorded._" / "_No salient pages in last 14d._") that
refreshEntity stamped with last_refresh. The false negative then
survived every subsequent TTL cycle, indistinguishable from a genuine
zero-rows result. Now failure returns null, so cmdGet's existing
missing/stale-fallback machinery reports the true state — matching what
fetchGoals and fetchSimplePage already do on failure.
Also adds an Array.isArray guard in fetchRecentDecisions so a malformed
payload ({pages: {}} etc.) classifies as failure instead of crashing
refreshEntity mid-refresh; a genuinely empty pages array still renders
the honest empty digest.
