Move the per-account INBOX-IDLE + secondary-poll loops out of the supervisor into a self-contained AccountRunner (start/stop/teardown). The startup supervisor now launches one runner per live account. Pure refactor, no behavior change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""Per-account sync runner (refactor §4).
|
|
|
|
An ``AccountRunner`` owns the long-lived sync loops for a single account and
|
|
exposes a small ``start`` / ``stop`` lifecycle. This is a pure extraction of the
|
|
loops that previously lived inline in the supervisor — behavior is unchanged
|
|
(INBOX IDLE + secondary CONDSTORE poll, each self-healing with backoff).
