Subject: [PATCH] fix(logs): render plain log notices verbatim instead of
 mangling them as timestamps

A plain message with no timestamp/level (e.g. the Windows 'Syslog is not
supported' notice) was parsed by the app-log branch, which took the first
three words as date/time/level and dropped the rest. Match the strict
'YYYY/MM/DD LEVEL - body' shape only, keep other lines whole, and drop the
leading separator when there is no stamp or level.
