Closing the capture store at shutdown now runs under the store lock and is
final: a monitor recording or scan batch still in flight gets a capture
error instead of creating a new temp directory and restore subscription
after the cleanup.
A well-formed queue cursor this process cannot verify (opened before a
ComfyUI restart, whose cursor secret is per process) now answers 409
review-conflict with the current total, like any other stale page, instead
of an uncoded 400. Malformed cursors stay 400.
