Deluan 9f216f624a fix(persistence): also try a numeric colon prefix as a plain path
'1999: A Different Life/01.mp3' parsed as library 1999 plus a truncated path
and matched nothing. The prefix is ambiguous, so search both ways.

Also buffer the json branch of 'missing list', which wrote a syscall per row.
