_scheduled_poll_once selected rows WHERE status='pending' and only wrote
status='sent'/'failed' after the SMTP send and IMAP append completed -
no atomic claim in between. Two overlapping callers (the in-process 30s
poller and an externally cron/systemd-driven 'odysseus-mail
poll-scheduled', or the CLI run manually) can both SELECT the same
pending row before either UPDATEs it, and both send it. _start_poller's
own docstring already names this exact risk ('avoid two copies of
_scheduled_poll_once racing on the same SQLite') but nothing in the code
enforced it - it was advisory only.
Add an atomic per-row claim: UPDATE ... SET status='sending' WHERE
id=? AND status='pending', proceeding only when rowcount == 1. The
loser of the race sees rowcount == 0 and skips the row instead of
sending a duplicate.
Adds a regression test that drives two real threads through the real
_scheduled_poll_once against a shared SQLite file, synchronized with a
barrier and a widened send-path window, and asserts exactly one send
fires. Reverting the fix makes the test fail reliably (5/5 runs); with
the fix it passes reliably (5/5 runs).
