common: buildIndex records when its last completed scan began

`meta.scannedAt` (INDEX_SCANNED_AT_KEY, in lib/stats.ts so buildStats need
not load the index builder), written only when a build completes. buildStats
reads it to tell a video downloaded since the last index build from one that
build saw and did not index. Additive: the index schema does not move.
