Trackers sharing a prefix but with materially different lifetimes
(e.g. session vs 1-year) were incorrectly merged into a single
prefix pattern. Port the snap table from cookie-utils.ts into Go
and use it to bucket durations so only trackers that display the
same human-readable lifetime can merge. Update the unique index
to include COALESCE(max_age_seconds, -1) so prefix patterns with
different durations can coexist.
