'.' was used as a sentinel for 'not yet fetched' in the SELECT query,
but it is also valid reply text. This caused any post where a reply
text was literally '.' to stay in the work queue forever.
Also fixes the fan-out UPDATE guard: previously it used
IFNULL(replyText, '.') <> @newValue, which would overwrite '?'
(confirmed-empty) rows with '.' when processing a dot reply elsewhere
in the reblog chain, pulling completed posts back into the queue and
causing the remaining counter to increase.
Changes:
- Remove OR replyText = '.' from GetRepliesWithFilledText SELECT
- Restrict UpdateNoteReplyText fan-out to NULL/'' rows only
- Use '?' not '.' as null-coalesce fallback in UpdateNoteReplyText
