docs(hono): verdict anchor on the catch-all — read ADR-0076 OQ#9 before splitting into per-prefix mounts (#3608)

The first place anyone (human or agent) tempted to "fix" the catch-all
looks is this line, not the issue tracker. Anchor the #3576 verdict and
the #2852 RLS-leak failure mode here; reopen conditions stay archived
on #3608 (closing as deliberately-unscheduled).
