chore(storage): exempt the copied sqlite open sequence from clone detection

The jscpd gate flags the deliberately mirrored open/stamp sequence
against session-persistence-sqlite and session-query-sqlite. The copy
is the settled this-phase choice — this group is the third user and the
shared medium helper is deferred to the log-facet migration so the
session packages stay untouched (reuse audit in the design note); mark
the span accordingly.
