serveAnswer resolved binary-glob and crlf-glob through a fresh LogStore.openReadOnly per setting per round -- a full frame-header scan each time, ~11s per round on a 1.17M-artifact store, turning a clone into half an hour of server CPU. The snapshot's per-build config read now carries the pair, like the submanifest facts beside it; freshness rides the same (size, mtime) key. Server CPU for the same 181-round clone: ~34 minutes to 15 seconds. check-in: 262ca49578 user: dmestas tags: trunk
